I bought this m112 for my 01 swap and I'm thinking the shaft the pulley sits on should be threaded inside and mine are junked. but then I think when we changed a buddies pulley it didn't have a bolt that threaded in it to hold the pulley on, it was just a plastic cap to seal it off. I may very well be losing my mind because it's been awhile and to me there should be a threaded bolt holding the pulley in place.
Anyways, here's a pic of the inside of the shaft I'm talking about. Let me know what yall think.
