I need to know the size etc for the four bolts that bolt into the front fire wall on a 71 super. Also the size of the two bolts that bolt the hammerhead to the body. I have looked at several websites and come up with different sizes.

Also have bolted the body to the pan with all the bolts except ones for front fire wall and the A pillars both sides appear to be sitting high (have replaced heater channels and not welded A or B pillars yet. Bottom of doors on both sides align very nicely with heater channel, only room for seal. Any ideas.

Bulkhead should be m10x1.5 thread and 80mm long. Hope your captive plates in the channels are OK 🙂

Hammerhead will be M10 or m12x1.5 thread.
