I hope to only have a few more frame repair updates, since there's not too much to look at. I started working my way toward the rear of the truck removing the crossmembers in the frame rails. I also located the front crossmember to the frame rails. It has two locating pins that are about 1" aft of where the centerline of the axles runs. They are just under 3/4" so I measured it all out and put two holes in the frame rails to get it lined up properly.
I also drilled the holes for the core support and lined it up to the frame. That core support is the reproduction for the 61-64 trucks but in a later post, I'll be adapting it to make it work.
After I got that done, I started the process of de-riveting the rear of the truck. There are a bunch. I've found the best way to remove them is to cut them first with the sawzall and then grind off the remainder of the rivet. They are such a pain to remove but there is so much rust hidden between where the crossmembers meet the frame rails, so it just has to be done if this truck is going to last.
In the coming weeks, I'll be rebuilding the 9" rear, patching the frame rails in a few more places, modifying the core support for use in a '66, rebuilding the motor and hopefully getting this messy garage cleaned up a bit.
