I'm looking for a set of Offy finned aluminum valve covers for a 1961-63 Olds 215. The Buick and Rover versions use different valve covers that do not fit the Olds heads. Olds 215 valve covers use five bolts, the others use four. Thanks in advance.

 

You could try calling D&D and see what they have laying about. Worth a shot.

Yes, but I'm cheap.

For example, I was able to purchase one of their repro manual trans bellhousings for less than half the list price from a private party. It had been installed but never used on a running engine.
