I have a supposed to be SCJ C6 trans and the only ID I have is the cast tail & D in the center of the modulator cover. Is this a SCJ trans and if so can it be used in concourse resto for a 68.5 cj? If yes what color is the fill tube and stick handle? Also what tag should be on a 68.5 CJ? Yes there is no tag but it was bought from GT performance, (Gary) many years ago.
