Having removed the centre section from the Escort prop i got with the donor, i have found what i believe from experience to have a siezed or partially siezed UJ, as ones all floppy and one sticks a bit.

What other props fit the MkII 4 speed box?? Preferably with removable UJ's

Or how much approximately to have one made?

I may have one for sale if you are interested. I had it made new by Autoprop last year and it has been used on my car for 1500 miles only. It's a proper job with circlipped UJ's, and it's fully balanced.
Let me know if you are interested and I'll send you details of the length etc.
