Thanks guys.

I think I can reuse the sleeves from the quick jacks.

The quick jacks had high carbon all-thread, but they are 7/16" (I think). They are larger than the over rider bumpers.

I can get all thread from Home Depot, which I will probably do while I wait on what I need from McMaster Carr. I feel weird using something soft for the bumpers. I suppose it doesn't really matter. The bumpers are mostly for looks anyway.
