Nylon should be OK but since there could be situations resulting in higher temps or maybe stress thru and around the bushings I would go with a phenolic or bakelite electrical grade product.

Do a search at McMaster-Carr for electrical grade insulating spacers and also washers. There is a fairly decent selection but if there is not a convenient size spacer available bulk electrical grade Garolite is also available in both easy to machine and higher temp range rods, sheets and tubes. The high temps are a bit harder to work though. If the sleeving is a thin semi flexible or woven type then search for standard wire insulation sleeving
