I currently have a 1970 dashpot & bracket off a 455 Riviera on the for sale forum. On the back side of dashpot it has US PAT 2657038, 2862702, 2894740 FF MFG CO. Can anyone tell me for sure if it would be the same as a 1970 455 GS? I know the bracket is different. From what I've researched it may fit quite a few years and engines. It would be nice to let potential buyer know! Thanks!
