Strut Bump Stops?
 

Anybody know the Energy Suspension or Prothane part numbers for the bump stops at the top of the strut rod for a Fox body? The stock bump stops are these huge metal caged, rubber stops but I've seen them replaced with smaller diameter polyurethane stops that just slide over the strut rod. I called ES but their tech idiot said he didn't show anything in the catalog.

Thanks.
