i bought a motor a while back and my rb25 came with a rb20 tranny.. for some reason the rb20 tranny bellhousing isnt long enough or something is wrong and wont clear the rb25 orc twinplate i bought. idk if its just me, or what.. it seems like the throwoutbearing is bottoming out not allowing the motor to seat all the way down. the tranny spins freely when it is on as far as it goes but there is still a 1/4 to 1/2 inch left to go. anybody have any ideas or solutions??im thinking maybe an aftermarket bearing isnt as tall as the stock one?
