I did what Sweatdreams discribed, only I did it on a nine inch housing. I had a Ford logo on about 1/8 steel from a shipping rack. A fork lift knocked it off the rack, and I didnt want anyone to trip over it. I cleaned it really well, and ground away all but the oval, then gently heated it to conform to the rear of the nine inch axle housing. I sweat brazed it on, and gently hand filed all the brass that showed. It held prime and paint with no problem. I had a Mopar fan convinced it was a rare Lincoln signature housing. Shame on me!
