Help with mystery front driveshaft

[Shankster]

Because mine is cup-shaped (not flat) for the stock Liberty driveshaft. I also have a spare XJ tcase with a 4bolt flat flange.

Thanks for the pics - my TC flange looks just like the top one but with 6 threaded holes instead of 8. You've reassured me that I could go with a standard driveshaft if it came to it. And that XJ 4-bolt flange is a different pattern than mine - as I said, mine is a 6-bolt "pattern" on the driveshaft but with only 4 of the holes drilled and I only use 4 of the 6 drilled and threaded holes in the TC flange.
