As title really, i've fitted a later 3.9 R180 diff in my ver5 type r to match the new ppg build with new ratios from chy at pennine but on fitting the prop have discovered that the holes dont line up? Would a lter prop be the best bet or is there another solution? Cheers Neil.

 

Undo the large nut on the inside of the flange on the diff, and swap it for the one on your old diff

 

Thought about that mate? Sold my old diff already? I did try to get it off but i think it needs a puller to remove it?

 

Yes, you need a puller. I delivered the flange and prop to a mechanical shop, they drilled new holes with the correct diameter.
