Jim, do you have to use a turned down bearing retainer for a chevy T.O. bearing or can you just use a toyota T.O. bearing? Asking because I have a couple of those plates in my mini hoard and I thought I was good to go with a chevy bellhousing and then an 11" clutch. Set me straight buddy, I just read this and got confused! Thanks -MattLifelong in Tenn., before you sell those 4 speed trannies, remove the front bearing retainer from the tranny that was mated to the Downey bellhousing adapter. Why; because when you and I come to some agreement on the price of the Downey adapter, I will need that bearing retainer with the adapter, it was custom machined to work with that bellhousing, and as I recall, was turned down to take a Chevy T.O. bearing.
