Many of you know I am going through a driver's side floor pan rust repair.It is a 1989 Astro and those where known in front crashes to have a crush area in the wheel well and therefor trapping the drivers feet.I've got a second sub-frame to build up and while I repair the floor pan,I'm thinking it is a prime time to reinforce both the sub frame and the floor pan.Looking at the sub frame,seems easy to reinforce that,but the leaves the floor pan/body to make stronger.I found out like most GM floor pans,it is made out of 19 gauge.Hard to get dumb idea.

Bottom line question is what to do to reinforce the wheel well floor pan area??.
