On my '64, even though it was a straight axle, the farmer had cut up a twin I cross member, and fit it between the frame rails with a thousand washers for shims,so he could use the motor mounts for an FE.
Both my trucks had the obligatory chainsawed-out radio hole
My 64 had a bus driveshaft with a brake drum on it
My 63 was supposedly built by a body man, who didn't straighten out one single dent on the front of the box/back of the cab before he painted it.
It also came with some goofy K-mart digital add-on speedo, which he cut a hole in the dash plate for. I put a new gear on the cable on the transmission and the original speedo has worked fine ever since. A new gear probably cost about 1/5 of the price of the super-cheesy aftermarket speedo.
The cab gas tank was moved to the rear of the '63.
So, the PO made some humungous welded Aluminum speaker boxes that took up the same space as the gas tank used to. Used 150,000 screws to hold them in. After i spent a whole summer removing the hideous creations, I could move my seat back 2" further (important in these little cabs) In addition to that, he cut speakers in the doors.
There's more but that should get us started.
