So happy I came across this thread. I was also missing that rubber bushing at the lower radiator attachment point on my '90 62, and this bushing fit perfectly. Yes I also tossed the metal sleeve and used a M8 bolt with a washer to try to help spread the load and it worked like a charm. Thanks...
he was offering it to me for $22K. I was the high bidder on it on BAT and was in discussion to buy it and someone got a deposit to him before I did. I hope it works out for whoever ends up with it.
