Quick replies; Tinman68, I can't wait to help you on you're x-member. I want to ride that thing! Whytesmoke, The material is 16 gauge mild steel it was around $60 bucks, here in N.C., for a 4' by 8' sheet. Vonratty, I've done 4 of these firewalls and each one is different in the way of pedals. There isn't much problem if your running an automatic (one less pedal). The tightest I've done was my 34 sedan because the car is so low and the motor is so wide. I'll be posting the pedals in the 35 soon, just mounted the master cyl. yesterday.
