Hi, after putting a screwdriver through one of my side plates while trying to scrape off the rust on the inside, I need to replace both. Has anyone had any experience with reproduction ones? Wadhams have a repro one at less than half the price of a genuine one. I am on a proper budget rebuilding the engine but need it to as good as I can get it without false economies. Does anyone know of anywhere cheaper to get these? Thanks Steve.
