Just did mine:


However, when I lowered and removed the cross member I checked for the shims and there were none on my '87

So according to the WSM, when installing the tranny I checked the measurment by lifting the transmission in the middle of the case far
enough that there is a gap between both
transmission mounts and the cross member.
I measured this gap on both sides and it was the same. (therefore I concluded I did not need to shim)

I had no shims on my GTS before. That's probably the reason why my old driver side mount was 4 mm shortet than the passenger side.
But when I installed the new mounts I had to use shims to spread the weight evenly. Driver side 1 mm and passenger side 4 mm. I used shims from my local hardware store.

I had another look yesterday and tried chaining two ring spanners together, still couldn't budge either top bolt. I'm going to try a 19mm crows foot (if I can find one) and see if that gives me better access.

One my third attempt at this job I finally succeded. The rather expensive Crows Ring spanner was no help at all. In the end the only way I could get enough leverage on the ring spanner was by undoing and tying the half shafts out of the way. The six bolts on each flange take me about 5 mins each to undo and another five to do back up again, so that's where 2 hours went.

Then to break the top bolt free on one side I used the hydraulic jack against the spanner. On the other side I used a two foot extension. Space is so limited that I found I had to use my fingers to remove and re-instert the bolts, although I did manage to use a gear-wrench on one side.

There were no shims on mine and the mounts looked pretty similar to David's, with the addition of a thick coat of oil and dirt.

I'd rate this job as tedious and tiring, with no guarantee of success.

I am glad to hear "no shims" I was worried that maybe my car was incorrect from the factory or removed by the PO. I was fairly sure that the PO had never done any work on the rear end of the car. (I am the 2nd owner) I spent a considerable amount of time trying to make sure I was reinstalling everything correctly.
