I recently acquired a 1971 F100 long wheel base Super Custom, with a 302 and 3-speed automatic.
The truck appears to be in decent condition. Rust isn't too bad. There is some rust by the hood hinges and the bed has a few holes.
The previous owner believes it has a 5.0 from an 80s Mustang in it. I'm not sure yet though. I'm going to run the casting numbers to try to find out for sure. Based on the VIN, it did come with a 302 though.
The bad: Here in Missouri, we have to get safety inspections when titling vehicles (if you're moving in from out of state and the title is in your name you only have to get a ID/OD (VIN/Odometer) verification done.
So, I know the truck is going to fail the inspection for the following items:
- Crack in the windshield. I imagine the only place to pick it up will be online? I can't imagine the local auto glass stores having F100 windshields in stock. Also, who'd install it? Any windshield installer?
- Steering is very jumpy. It's possible the fluid in the steering box is low or something (I don't know anything about them yet), or I might need a new steering box.
- Rear brake line is apparently ruptured along the frame somewhere, so the front brakes are the only ones working right now.
- Some indicators and a brake light are out, as well as one of the license plate light housing is missing.
- The horn is inop (not operational). There's an aftermarket "Grant" wheel on it.
- The engine. The inspection station said if it is from an 80's Mustang, I'll need all of the emissions control systems (cats, filters, whatever...) from the 80's Mustang.
Since the truck is pretty dang old, I'm sure it may fail a few of the other 30-40 inspection items.
So, things aren't looking to good which is a bummer. It's crazy to me that Missouri requires an inspection on a vehicle like this, but I guess it's for safety reasons (or revenue).
Here are pics from when I bought it.
to the family from south Texas... we like to see pictures so post some soon... I would not tell the inspection place that the engine is from a newer vehicle, that way you are under grandfather law, which means that the vehicle should pass with the equipment it came from the factory with... also check your tie end rods that may be the steering problem... good luck...
