yeah i emailed one of marlins guys and they said itll work no problem. He said the new set up is the same as thickness as the bearing and hub on the older style just in a one piece. and the clip on it is different. Idk why it keeps comming off tho. everything is on right. i guess we'll just wait and see. from what little i did get to drive it i LOVE the marlin 1200hd clutch!! and the new t100 brake booster i just put on. now i just gotta get the proportioning valve and rear discs on!
