I am going to be installing a rear bumper on my 1994 Acty that attaches through the leaf spring bolts. My leaf spring bearings are pretty well shot. I am on a waiting list for a stock replacement set with a supplier, but was also investigating some poly universal bearings from an on-line supplier. The only problem is that I need the dimensions of the bearings to see if they offer a generic set that will fit. Does anyone have the dimensions of these bearings? Thanks!
