Verify 66 RC26 Configuration

[Jeff Z.]

I couldn't find a picture of a 66 RC26 cap in the archives (only an older design 65 cap). Can someone verify the attached is correct for a 66 SB non AC car.

Thanks
Jeff

Jeff - The photos you and Craig posted of the AC RC-26 Radiator Pressure Cap covers are typical of the RC-26 cover stamping configurations introduced with the 1966 Production year on the 66 sb Corvettes and carried on into the early 70s. As far as I know there are no specific Production year configurations related to the orientation of the 15# RC-26 stamping on the ear but it will be on one of the ears. The same goes for the AC stamping as it will be as shown or located 180 degrees from the position show. Examples I have seen that have the AC to the right of the rivet have 2 circles around the AC as opposed to the single circle in the examples shown. Other examples I have seen on 67s have both the AC and 15# RC-26 stamping located together with the AC to the left of the rivet and the 15# RC-26 on the left ear. Pete
