I owned an 87!for about 8 years. I took the hard top off every spring and put it back on every fall with no issues. I followed the directions in OM and 0 leaks, 0 fitting issues, and no problems. If my recollection serves me correctly all go,to were the same, but it was recommended to install the 2 bolts going into the door pillars first to help line the holes for the rest of the bolts. I am/was not aware of a go,t that triggered the rear windows operation. However, there was a plug that needed to be put together for the rear window and wiper to work.
I had a custom soft top made for the afternoon downpours. Go for it, but follow OM instructions for years of "topless" fun! (That's what "she" said!) :reddance:
