The large end yoke measures 7-1/2" and 7" schedule 40 pipe is 7-5/8 od. 7" pipe is not that common and i had a piece if i can find it, simple enough to turn it down to fit if not rolling a band out of flatbar isnt that hard then true it up in the lathe.

The other end isnt critical and a piece of 2-1/2" pipe fits fine
