Many moons ago, when the prairie grasses grew tall and the buffalo would drown out your wife's jabber; I bought what I believed to be an R-Model oil cooler--it had cobra cast in raised letters on the side. A reputable vendor, lets call CoAu, Inc. sells a complete kit it says is accurate in details. Should it have the COBRA lettering on the adapter? Anyone recently buy such a kit, and what was your experience, and satisfaction?
