The internal splines on my L455 flex-plate (699154) to pump are stripped. I tried to find a replacement but salvage companies and parts sellers I have contacted were out of stock and could not give a lead time for availability. My local machine shops I contacted said they could not do anything with internal splines. Does anyone know where I can find a replacement flex plate or knows of a shop that could repair/replace the female splines? Is there another repair approach I should consider? Any advice would be appreciated.
