Hey everyone, I'm looking to see if anyone here has or knows of someone looking to get rid of an sm420 to LC 3sp adapter plate. I'm striking out pretty hard on locating one because apparently they have fallen out of demand. If anyone has any leads, I'd greatly appreciate it. Thanks Mike D

My 77 Fj45 has an SM420 transmission and I've bought a H42 to swap back into it as the 420 is in bad shape. Does anyone have insight on modifications that would have been done to get the Chevy trans in there? Or could the h42 be bolted back it into the housing and go from there? Thanks in advance!
