I know lots of people would love to have one but can't shell out that much money. I found this guy who sell's a replica of the Art Carr version. If you want full manual reverse pattern valve body with compression braking, get one of these. The best thing, it's half the cost http://cgi.ebay.com/ebaymotors/ws/e...rd=1&sspagename=STRK:MEWA:IT#ebayphotohosting Oh, I don't know the dude nor do I make any money off pimping his products. This is just for info purposes only.
