The 2" Dougs I have are nice and fit well on my 65 dodge coronet with the EZ-1 heads with an RB block & 4-speed. I don't have an 11" clutch - just the 10.5. They are almost identical to the tti's only much better quality. I also have my motor in the stock location - if you have a newer k-frame then the Dougs probably will not work.
