What’s up guys! So I’m having an issue with my 1971 442. The driveshaft hits the floor over bumps. Looks like maybe the floor was replaced. The car has been fully restored. Suspension is all new(stock). Any ideas what it may be? Is there multiple types of transmission mounts? It has the 455/th400 package

What transmission mount is in it? I had one of the poly aftermarket ones with thick flat spacer do the same thing. If that's the case remove the flat spacer.

is the body centered on the frame? I had a car where the body was ~1/2" offset on the frame and the DS hit one of the seatbelt bolts ...

My 1965 442 did that when it was new from the factory (Lansing). Apparently there was a bit of a wrinkle in the floor pan that wasn't supposed to be there. The dealer "cured" it with a long punch and big hammer.

thanks Ozzie I’m going to Jack it up, remove driveshaft and see if I can modify that area a bit
