so finally got new tensioner/idler/serpentine belt installed....while doing, noticed two things....upper engine mount, nearest brake reservoir, the rubber bushing is cracked and degrading....looking at schematic a TascaParts, not sure what part to order...is bushing available separately, or do I need to purchase bushing already pressed in to bracket...I'm thinking bracket from firewall to bracked on engine... second query...some measure of wobble in PS pump pulley...pump functions normally and does not leak....is pulley available separately...?? have friend with special tool to remove/replace pulleys...
