okay, heres what I've got going. Ive got the full floor pans for my '66 and thats all fine and dandy, and I have the firewall extension pieces because that area is really rotted and I was wondering whats the best way to get under the dash so i can cut out the bad part and weld in my new firewall extenstion pieces? Is there and easy way to do so (i.e. pulling part of the dash out, pulling the the engine out ang going at it from the engine bay, etc.) If anyone has any experience in doing this, any help would be GREATLY appreciated. I wish i had pictures, but I dont yet so if you think you can help feel free to ask questions I'll try and explain better. please help me! I really wanna get my stang rolling around!
