I didn't think there was a difference. I think the guy who said the seal adapter wouldn't work on a 68 or so American spindle either used the wrong seal or rotor, or was sent the wrong adapter. Those are the only reasons I can think of it wouldn't work. He said the rotor seal pushed all the way over the adapter... something definitely not right! Hope to hear from the guy and find out what the real problem/solution was. -------------- Date: Thu, 24 Apr 2008 09:58:55 -0700 (PDT) From: Tom Jennings <tomj@xxxxxxx> > I can't tell the difference between a 63 American > and Classic drum brake spindle, but I haven't mounted a Ranger There is no difference. I just put 74 Gremlin drums on the 63 American. Bolts on, same height, Gremlin grease seal and bearings fit in the AMerican spindle. Most definitely, 63 Classic == 74 Gremlin. As far as I can tell, other than the later Matador etc "big bearing" spindles, all AMC/Rambler/Nash spindles are exactly the same EXCEPT that there are two heights of the base (thickness where the bolts go through) -- a "tall" one used on many (but apparently not all) AMC factory disc brake setups. The reason is to clear the disc brake dust shield. THat's the only difference and the only reason for the height difference. -- Frank Swygert Publisher, "American Motors Cars" Magazine (AMC) For all AMC enthusiasts http://farna.home.att.net/AMC.html (free download available!) _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list
