does anyone have a part number for the vette servo thats talked about. i checked GM part numbers and all new vette servos are the same part number as the one already in my truck. Any one know for sure that a trailblazer stall will fit to the flywheell, I assume when u say trailblazer stall u mean theone for a 4.2 inline engine because the v8 trailblazer has the same one as my truck also.
