The cover in the ebay ad looks nice, but is far over priced. He also states that it can be used to advance cam timing. Only if you have the matching cam gear (only available from South America) which he does not state. He also states the cam can be swapped by turning the second cover. That can't be done either if the balancer is bolted on. There will be no access to the bolts hidden under it.
Got a cover in the works that will be far cheaper than that, made in USA coming by end of summer.
