Thanks a lot Matt!! For looking in the parts book and checking as well as giving a good reasonable explanation to support the info. I have a couple parts books here, but just don't have time to do 100% of the research myself. The list is a great research tool, one reason I took it over rather than watch it falter and die. -- Frank Swygert Publisher, "American Independent Magazine" (AIM) For all AMC enthusiasts http://farna.home.att.net/AIM.html (free download available!) original message--------------------------------------------- Date: Sun, 01 Jan 2006 12:07:29 -0500 To: mail@xxxxxxxxxxxx From: Matt Haas <mhaas@xxxxxxx> Subject: Re: Two Piece Front Hub/Drum Assembly I just took a look at my parts book and there are some cases where the same drum used on one model for the front is used on the rear of another but there's also the fact that both Bendix and Wagner sold brake parts to other manufacturers (Ford, Volvo, Studebaker, and International, among others) so separate hubs would let them use the same drum for different makes. Also, I would think that it would be far easier to do the casting and machine work on individual parts than it would be one big assembly. Rotors, on the other hand, are a different story. Both one and two piece assemblies have been common for most of the time they were around with two piece being more common now since most vehicles are front wheel drive. Matt
