Need 4-speed Help

Have you considered trying a stock bellhousing? Maybe the ss is no good/bent and that's why it was sold at the swap meet!
I've never had a problem with McCloud products, never did try Hays.
If it works on a stock bellhousing, then order a new ss and bite the bullet.
I know that it's extra work swapping bells again, but it should sort this problem out once and for all. You've done it 5 times allready, what's another 2?
I bet you are getting good at it by now and being pissed off at it makes the tranny manhandling easier!:-D
