Thanks. I'll try to get a pic up tonight after work. I was taking the measurement by laying the tape on top of the passenger side frame rail, nosed up against the firewall and stretching it right to where it's welded to the radiator support. Sort of tough to get an exact measurement since it's tight in there but, I figured something down to the 1/16th would work.
I pulled the motor/trans out the other night to inspect the area because I knew the rust was getting bad, but didn't realize just how bad. Actually, I'm very lucky I did this because the end of frame rail rusted (damn battery acid) and has separated from the rusted out firewall section. It would have been pretty ugly if that right front let loose while driving.
I realized this morning that I probably should have posted this in the "Brakes, wheels, suspension, chassis" forum but don't think I can move it now. Moderators - please move if you feel it should be over there. Sorry about that.
