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.
