I recieved my ACT2600 clutch from slowboy racing today. And it came with the metal sleeved TOB.. So I went to mitsu and got the plastic sleeved one... When comparing the sizes.. The OEM TOB is much smaller than the ACT TOB. Has anyone else noticed this to be true before?? I just want to make sure I install the correct TOB. Will the OEM one still fit even though it is smaller than the one ACT uses???
