I have some used OE ones and a few of TFS replacements. TFS ones are not correct and usually pull away from their gruves. But they are better than a torn or missing one until you can locate a good one. I have purchased old 88 calipers here in the mall just for the slider boots. If you want a TFS one PM me your address and I will send you one for comparison.
Use denatured alcohol to clean the old one up. It will not ruin them. I cleaned one with gas once. It almost doubled in size!!
