When I made my bushings I used a high temp garolite rod from McMaster but probably the regular rod would work as well. At 335F the high temp rod is rated roughly 100 degrees higher than regular and price wasn't too much more so I opted for the extra.

I doubt the pump and bushing ever gets even exposed to the regular rated temp being positioned that low on the block and in the airflow so not sure high temp is necessary. The originals were a phenolic or bakelite and paper composition. No idea what temp those are rated but garolite or the fiberglass epoxy resin compositions seems to have taken the place of the old paper formulations.
