Chopped 2.5" off the bottom of a stock truck pan to reduce it to the same depth as an f-body pan (mainly didn't want to pay for a used f-body pan + shipping).
Initial cut of trans tunnel, but shows relief cuts for an old version of the trans x-member. I eventually went to a better x-member design and eliminated those stock x-member floorpan humps, making the foot area flat.
Final version of the trans x-member..
Driveshaft loop AKA subframe-connector-crossbrace
Made a weld-in labyrinth sump for the fuel pump.
Made a fuel pump holder. Made it capable to hold a second pump, but only have 1 in there for now.
Also snipped the corners of the tank for 3" tailpipes and future 315 tires, at a very low ride height.
