I am looking at tubing my core support. But why must you toss the inner fenders? I am looking to do it to clear out the rad support (already butchered) for a nice big rad, tranny cooler, A/C condensor. I have some perferated sheetmetal that I was going to do the inner fenders with for a little better heat rejection after the A/C goes in, but I don't plan to ditch the inner fenders. The battery has already been relocated to under the passenger seat.
