I need to buy a M/C for one of my cars, a '73, and guess I'll be going with something other than ATE. Does anyone know what the differences are in the two below?

One is a 19mm and the other didn't say. So probably a 17mm |

I was under the impression that those cars used a 19mm MC like the 911 - true or not? Thing is they are differnt model numbers tho. |
