AC Pulley Diameter

[Yardley]

Which is the AC pulley diameter for a performance axle? The 5" or the 5.75"? I think the larger one, right?

Yards,

The 70 GS's came with the large 5 3/4" A/C pulley. Can be used on other years of xourse. At one point it was available at Autozone. Not hard to change.

HTH.

The standard 1967 Riviera and Skylark had the 5", but the Riviera GS & GS400 had the 5.75". Hope that helps. It is really getting hard to find a new replacement 5.75" pulley/clutch assembly these days.
