The 143 is a bolt in on the starter.The DD Hemi was iirc 178 teeth.My buddy has one in his Runner.I run a 143 with Lakewood.Did run the stock bell years ago.No problems with a mini.My stock bell was from like a 69 or so Runner.Just remember if it has the plastic cap it usually has to be tossed.Some blocks need the studs cut down a bit also.Rocky
