I'm shopping for my first truck and I've found a 1970 D100 with the right "feel." The seller says it has a thumb-sized hole in one cab mount that he thinks could be patched with a 2" by 1" piece of metal. First of all, does that sound realistic? Second, what's involved in patching a cab mount? Would I have to lift up the cab? How do you do that? I'm waiting for a picture before I go look in person. Any other comments on a truck like this? Here are some pics for fun.
Pretty normal fix. I replaced the cab mount on the Passenger side and the entire floor on the driver side. All the pieces to fix this are available from Kenny Exline. If you are looking for full restoration, then removing the cab is a good idea to replace all the pieces of the support and mount. They are most likely damaged as well. See all the parts here. http://www.exlinecustomauto.com/custom-services.html
But if the truck is supposed to be restored already and you are paying as if it is restored, you need pictures of the supports and floors to see how much rust is there. Because it is possible to just replace the floor and make it look like it is fully repaired which it may not be. You can see that the trim line from the cab is lower where it meets the bed, that is a tell tale sign that the cab mounts, rubber isolators and/or supports are suspect.
Thanks for pointing out the misalignment between the cab and the bed. I did notice the rust in the door corner, but my thought is that a door should be easier to patch than a cab mount. I'm pretty sure I can handle areas that are easy to access, but removing a cab is probably more than I want to take on.
Being in a place like Maryland will be difficult to find a truck that doesn't need rust repair. A large portion of these trucks have the front cab mount rust due to the poor design that allows water to pool in the divot. That includes trucks that spent their lives in a areas where rust usually isn't a big concern.
That truck has an older bed on it and there will be mounting holes under the trim.
