Title: 69 Starfire Base gasket
Post by: RED ALEXI on 04 June, 2017, 07:41:29
The multi gasket kit I got off fleabay has two base gaskets. Both would seem to fit, but are of different thicknesses. One is quite thin, made of straight, plain gasket paper, the other one is more like cared, blue finish and slightly larger on the outside diameter. Is this the correct one for a square barrel ? does it matter, or is it another one of those "Oh my GOD, don't whatever you do fit the.." moments ?

The paper one was listed for the C25 and in October 1967 it was changed to a thicker gasket from a composite material.

Part of parts service bulletin G45 from October 1967 attached below.
