ok so i took my homies 78 caprice and took the lil tranny out and put my old TH400 in her but the tranny cross mount doesn't seem to fit. sooo i need to know if there was a 4 door 78 caprice that came with a OEM TH400 so i can get that mount if not are there anyother ways i can get it done and over with? its the last speed bumb besides getting the driveshaft shortened.

any and all help would be greatly appreciated thanks.
