I am compiling this information now (well, yesterday). I have a 1977 AMC15 10x1.75" set here. The center hole size differs on 9x2, 9x2.5, and 10xanything drums. I'm hoping there's just three hole sizes, but my early American may be a 4th, if so, there are likely more. I hope that all 9x2's are the same, 9x2.5, etc... but I don't know yet. Bigger drum, bigger center hole seems to be the pattern. There's simply a lot of data to put together. I'm working at it continuously. I think after I get the data that John gave me (thanks again!) in, and some of this data reduction crap done I may publish it with some years missing. I can fill thos in on a second pass. _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list
