I’m facing several issues and wondering if it’s better to fix or sell my truck.

Bill avatar

Bill:

That’s a tough decision, but let’s break it down. The 1986 F250 with a 351W is a classic piece of Ford history. Here are a few things to consider:

  1. Nostalgia and Sentimental Value: If you have a personal connection to the truck or if it has been in your family for a while, that can weigh heavily on your decision.

  2. Condition and Repair Costs: Take stock of what needs fixing. Is it mostly cosmetic, or are there major mechanical issues? Sometimes, it’s cheaper in the long run to fix what you have rather than starting over with a new vehicle.

  3. Market Value: Research the current market for similar models. You might be surprised by how much classic trucks are selling for these days. If your F250 is in decent shape, it could be worth a good chunk of change.

  4. Your Skills and Time: Do you enjoy working on vehicles? If you have the time and the know-how (or the willingness to learn), restoring it can be a rewarding project. Plus, there’s nothing like the satisfaction of bringing a classic back to life!

  5. Community Support: Don’t forget about resources like the Bullnose Ford subreddit or the Bullnose Garage. They can offer insights, tips, and even moral support for your restoration journey.

If you decide to keep it, maybe tackle repairs one at a time, starting with the most critical issues. But if you lean toward selling, ensure you get a fair value based on its condition.

Whichever way you choose, just know that classic trucks like yours are always worth some love and attention! What specific repairs are you facing?

Most of the dashboard lights are out, the steering gearbox is failing, and the transmission and clutch need work. The bed is uneven and I lack a front bumper and tailgate. My tires don’t match, and the firewall is separating at the clutch pump. The left rear blinker is out, and the previous owner installed a Ford Expedition seat that’s unstable. Plus, there’s no headliner.

Bill avatar

Bill:

Wow, that’s quite a list of issues you’ve got there! It sounds like your F250 needs some serious TLC, but with a bit of determination, you can bring it back to life. Let’s break down those problems and see where to start.

  1. Dash Lights: Usually, this can be a simple fix—check fuses and the bulbs first. If those are good, it could be a wiring issue.

  2. Steering Gearbox: A worn-out steering gearbox can be concerning. Replacing it with a remanufactured or new unit is a good idea. Make sure to align the steering afterward for safe handling.

  3. Transmission and Clutch: If both are going out, it might involve more work. You could look into a complete rebuild or replacement. Make sure the clutch hydraulic system is also checked, as it could be part of the problem.

  4. Lopsided Bed: This could be due to worn-out mounts or frame issues. Start by inspecting the bed mounts and the frame for any damage or rust.

  5. Missing Bumper and Tailgate: These parts can be found relatively easily, often on forums or sites specializing in classic Ford parts. They’re a good way to improve the truck’s appearance and functionality.

  6. Tires: Mixing tire sizes can lead to handling issues, so I’d recommend getting a matching set as soon as possible.

  7. Firewall Separation: This sounds serious. You may need to reinforce that area to prevent further separation, especially since it’s affecting your clutch operation.

  8. Rear Left Blinker: Check the bulb and wiring first. If the bulb is good, it could be a grounding issue or a problem in the turn signal relay.

  9. Seat Replacement: A new seat can make a huge difference in comfort and safety. Look for seats that fit well and have good support.

  10. Headliner: You can either replace it or go for a DIY solution. There are kits available that are relatively straightforward to install.

Given all these repairs, it might feel overwhelming. If you’re leaning toward fixing it up, tackle one project at a time to avoid burnout. You can also share your progress with the Bullnose Ford subreddit; they love to see transformations!

If the thought of all these repairs makes you lean toward selling, remember that classic trucks can hold their value. Either way, just think about what’s most rewarding for you. What’s your gut feeling telling you?

You’re absolutely right; restoring a classic like your F250 can be a bit of an investment. It’s easy to underestimate the costs until you start adding everything up.

Here are a few ways to approach this situation without breaking the bank:

  1. Prioritize Repairs: Focus on the most critical repairs first—safety issues (like the steering and brakes) should take precedence. Once those are sorted, you can move on to the cosmetic issues.

  2. DIY Where Possible: If you’re comfortable getting your hands dirty, tackle some of the simpler jobs yourself. There are tons of resources, including videos from Bullnose Garage, to guide you through repairs.

  3. Source Parts Wisely: Check out local junkyards, online forums, or sites like eBay for affordable parts. Often, you can find good deals on used or refurbished items.

  4. Create a Budget: Make a list of everything that needs fixing and estimate the costs. This will give you a better idea of what’s feasible and what might need to wait.

  5. Consider the Long-Term Value: A well-restored classic can appreciate over time, so while the upfront costs may seem daunting, think of it as an investment in something that can become a labor of love.

  6. Community Help: Engage with the Bullnose Ford subreddit or other forums for advice and support. You might find someone who’s tackled a similar project and can share tips or even help you out.

  7. Take Breaks: If the project feels overwhelming, it’s okay to take a step back. Sometimes a short break can help you see things more clearly.

If, after all this, you still feel like it’s too much to take on, selling might be the better route for you. Just make sure you consider the market value before making a decision. Remember, whatever you choose, you’re keeping the spirit of classic Ford trucks alive! If you have more questions or need specific advice on a repair, don’t hesitate to ask!

What are the differences in crossmembers for the 1983 Ford F250 460 ZF5?


Bullnose Bill explaining the 1983 Ford F250 crossmember features.

This Q&A session is powered by Bullnose Bill, Bullnose Garage’s advanced AI mechanic.
Have your own question? Ask Bill!

Bill says:

Great choice with the ’83 F250! The 460 engine and ZF5 transmission combination is a solid setup. When it comes to crossmembers, there are a few differences to be aware of, especially if you’re considering swapping in a ZF5 or dealing with repairs.

  1. Transmission Crossmember: The ZF5 has a different mounting point compared to the older Ford transmissions. If your truck originally had a C6 or similar, you’ll find that the crossmember mounting locations and style are different. The ZF5 crossmember is typically more robust to handle the torque from the 460 engine.

  2. Engine Crossmember: The engine crossmember remains relatively consistent across the Bullnose models, but you should ensure that the engine mounts align properly with the 460. Sometimes, modifications may be necessary depending on whether you’re swapping from a different engine type.

  3. Positioning: When swapping or updating your transmission, make sure to check that the position is correct. The ZF5 is longer than some earlier transmissions, which might require adjustments to the existing crossmember or driveshaft length.

  4. Mounting Hardware: Don’t forget about the mounting hardware! Ensure you have the right bolts and brackets, as these can vary between combinations.

If you’re looking for more detailed visual guidance, I always recommend checking out Bullnose Garage’s videos. They have some helpful resources on transmission swaps and crossmember setups that can really clarify things.
