Soooo, When I bought the discovery I was told the front propshaft was a Great basin rovers HD. I pulled it way back then and it was green and in good shape.
Seemed accurate. I was a new rover owner

I have questions now. Pulled it again to recheck joints and now i see it differs from what i see online for a common d2 front propshaft at the transfer case end.
Is this a defender prop. Sporting a spacer? Im kinda lost.
juat trying to identify what im seeing here.

I shamelessly stole a pic from a old post on this forum showing the same area. My pic was blurry and theirs is great. Props to the camera mans skill.

If this is just normal. Plz disregard. Sometimes ima bit dense

 

The photo you posted has a spacer installed.
