Just got my M5R2 today at my local PullaPart $65.00 plus core. May be a good trans as is, (full of good clean fluid) but I will probably open it up to inspect it anyway. My question is... there looks like there is a provision for a throwout fork in the lower left part of the bellhousing. Im guessing some applications of this trans used an external slave cly???? If so what parts from what veh does it take to convert to external slave if possible?
