Some 83 thru 84 S-10's had a 2.5R motor. I am working on a motor out of a Chevy Citation (84) What I need is simply the cam retainer plate from any old junk motor and haven't been able to locate one yet because of vehicle age. I'm hoping to find one before resorting to re-fabricating one. This plate is located behind the timing gear on the end of the cam and is removed thru the two small holes in the timing gear. The lifter rods must first be removed and then the entire cam and gear and retainer come out as one piece.
