Thanks larry4406. Hump fits snug on the tunnel hump but lots of gaps on the floor pan. Great tip about leaving floor on trans brace.
Thanks Beekeeper, I was referring to your 70 Challenger rebuild thread and photos. Any chance you can run a tape to see how far front of shifter hole is from the firewall seam join ?
Only want to cut once. My diff is still in so I could attach the drive shaft and then measure the 4-speed to see where shifter sits. Easier than dropping the engine in. Small issue of not having a 4-speed my mean I need help from C-C members.
