Norm no longer makes rockers, he never made links... he made a replacement rocker.. I have a couple, and was sent one recently from another COG member for measurement,, so far I have the lowest version Norm ever made, but he didnt sell it, another mid distance one, and the one he sold as his product..
currently working on getting these quoted for manufacture, and production, but costs for time and material, and machining, are outrageous... Norm made these in his garage, and price never included his cost for his time..
check back in about 3 weeks, I'll have a price for a current production on a redux of what he made, and maybe with the upgrade to bronze oi lite bushing/bearing version, complete and ready to bolt on... but I'm just warning now, it ain't gonna be cheap (frugal)...
