Okey, I already took out the A6 and ready to drop the Z6. I have 1 problem, what mount do I use for the driver side? I tried swapping the A6 mount to the Z6 but it does not line up with the timing cover. Do I use the 92-95 mount? Thanks for looking.

 

I used the a6's drivers whole mount. and switched out the z6 one.

 

im doing the same thing with my 89 si
