HD Drive Shaft Installation - U-Joint wont fit?

[DiscoParty]

Looking for advice from anyone else who had nightmares of their stock drive shaft shooting through their Disco 2 transfer case, and purchased the Heavy Duty Driveshaft.

I actually bought mine from somebody who had the HD installed but the U-Joint went. I bought a new U-Joint but it didn't seem to fit, the caps were a tad too big. Interestingly enough, I pulled a stock driveshaft that I had on a parts rover and the U-Joint fit fine, so I put it on (It was my daily driver at the time, I get it). It be ridiculous not to use the HD driveshaft, so I'm trying to figure this out.

Is there a more specific U-Joint I need to order for the HD draft shaft? Anyone swapped one of these out and hit the same problem?

I've done heavy duty shafts on the front and rear (from Lucky 8 Offroad - sorry Rovers North), not one problem. The rear was a conversion to u-joints, replacing the rubber roto-joint. There are a few folks selling HD drive shafts and they don't all use the same size u-joints. So, unless you can measure the u-joints themselves, or the area of the drive shaft where they mount, and look up the u-joint in that size, you're pretty well stuck for an answer. Or, on the off-chance you know who made or supplied the shaft you have. On these Disco 2's it's usually the front shaft that gives out and goes through (and I do mean THOUGH) the transmission (ask me how I know...).
