Thanks guys, I appreciate the support.
Made some progress. Got the truck all cleaned out and torn down. Rolled out the old chassis and started to mock some stuff up. I miss calculated the first time and thought the corvette k member was gong to be way to narrow.
After some cursing and a lot of research, I remeasured and the width of the corvette suspension looks like it will work nicely with this setup.
Also, picked up some sheet metal and bent some new bed sides. Now we can get a better Idea of ride height and fender placement.
Decided on a 5" ride height. I like it low, but I don't want to do air ride. I think this will give me enough clearance for speed bumps and driveways while keeping the look. Going to try to keep it as flat as possible with no rake front to rear.
Hopefully that's it for demo work. Now the fun part. Fabbing up the custom chassis.
