I am replacing the clutch in my 96 truck. Thought I would replace the rear seal. My eingine does not have the bolt on crank seal housing. New Fel-Pro seal has steel installation tool with flange. I installed seal and recessed about 1/4" from rear crank surface, where flywheel bolts up. I am thinking it is ok, since rear crank flange appeared to be at least 3/4" thick. I drove seal in until flange on installer hit the adapter plate. did I install the seal correctly? Thanks.
