Am in the final stages of engine rebuild (2.0 -- early '65). Am afraid I've made a mistake from which I'm hoping to recover. I removed what I know now to be the axial sealing rings from both ( L & R) sides of the chain housing covers--destroying both in the process. Am having no luck finding source for replacement seals. Hopefully someone can point me the way to resolve this. Lesson learned--never assume a 40 yr old part is available. Axial sealing ring shown on page 51 of Bruce Andersons Performance Handbook---(three parts sources I tried all gave a big ? a what?? Thanks very much Steve L.

(Why removed? Covers warped--Glass sanded same, seals prevented sanding---Haynes manual suggested replacement,sigh)
