Ok, I am sure glad I didnt try doing this in my driveway! On the passanger side, the bolt seized to the bushing collar. I broke a 1/2 rachet and ended up taking it to a friends shop to use the rack, impact wrench, and more professional tools.

With the bolt seized to the collar, it was a pain to remove and the triangle bracket was "stuck", so the bolt had to be cut in order to free and reuse the bracket.

So the new subrame mounts are installed, but there is a 1/4 or so gap sticking out still. I looked at my other w123 (its a low mileage, 1 owner car that hasnt been worked on much) and the subframe mount is nice and flush.

When "pressed in" using a jack, the mount goes in ALL the way, but when you remove the jack, it pops back out a little bit. I was hoping that when tightening the bolt, it would draw the rest of the mount up so that it would be flush again, but that is not the case, so whats wrong?
