A 1995 Cobra R bell housing is the proper bell for the TKO 3550. As far as I know, the 3550 does NOT come with a shifter as the TKO500/600 do, so you'll need a shifter. Do the grind on the mount and you will have to measure, after the install to see if your drive shaft length fits correctly. If not, have the tube replaced at a DS shop (cheap) and that should be about it for Tremec specific parts.
