Thanks to all who posted on this thread I just replaced my vr without removing the alternator. You do need patience (surgical hands do help since it is a bit tight) and a mirror to do this but it is doable. You just gotta remember how everything goes and make sure everything is tight.

My main issue is that my alt has the vr with the oval connector instead of the rectangular connector as listed so after buying the rectangular one on Pelican I had to return it. Found the part on Autozone thanks to another thread posted here. I was surprised my local dealer didn't have the oval connector (or it wasn't showing in their systems as the part for my car so they didn't even think to look - I believe this part shows for the Z4). The bushes on the old vr were pretty worn as you can see below.
