I was thinking Delrin but looked up the thermal properties and they appear to be on the low side for tight exhaust clearance with high loads: http://www.sdplastics.com/delrin/delrin[1].pdf

I removed the GM Pitman arm and installed the Moog K6099 replacement Pitman arm on the car today and the Moog arm compressed against the header as it was tightened to the frame. The OEM arm had just over .25" clearance.

A bronze replacement bushing for rebuilding the OEM arm would be real nice in my situation.

Doug's D368 headers, GM OEM motor mount perches, Moroso 62150 solid mounts.

I made it on a lathe. It was a bit tricky getting the length just right so that the end cap did not over or under-preload the bushing/pin axially.

The grooves in the bore and face are for lubrication.

The cap was welded back on taking care to keep it seated square.

Carl - Was it a factory arm that you installed the bushing in?
