It’s a cheap one from O’Reilly. Number on part matches what it’s supposed to be. (B2272) Application according to their website is correct, (it covers about every a,b,c,e body from 63-72). I ordered it for my make model engine. I have to be missing something, problem is, the pic you took shows me something is different within the rubber mount. Next step is removing that rubber above tail shaft and see what it looks like.
