I am doing the same with a 84 and a 36 chevy truck the rear looks like a piece of cake I took 3/8 pipe cut it to fit where all the bolts hold the rear end to the corvette and made a jig by welding them all together with pipe the two bolt that hold the pumkin all perallel with the frame The jig fits right on the frame of the truck and lines up everything. the front is going to be a bitch. But thats next weeks project.
