RivNut Posted April 24, 2020 Share Posted April 24, 2020 (edited) The narrower one is 1965 and later. The OD of that hub is hub-centric with the ID of the register ring in the rally wheel (and the center hole in the standard steel wheel.) The wheel rides on the hub rather than the wheel studs and lug nuts. Edited April 24, 2020 by RivNut (see edit history) 1 Link to comment Share on other sites More sharing options...
arnulfo de l.a. Posted April 24, 2020 Author Share Posted April 24, 2020 Great! Thanks Ed that's what I was hoping for. Link to comment Share on other sites More sharing options...
RivNut Posted April 24, 2020 Share Posted April 24, 2020 You'll notice however that the holes in the brake drums are the same size. The 63/64 hub will fit snugly in the drum, but the 65 hub is held in place by the rivets and the wheel studs because there's gap between the hub and the hole in the drum.

arnulfo de l.a. Posted April 24, 2020 Author Share Posted April 24, 2020 I'm thinking you are referring to the collar that is closet to the mounting face of the hub.The 63,64 one is much wider than the 65 one and protrudes about 1/4 " from the outside face of the drum. That collar prevented my adapters from fully seating against the outside face of the drum. If you look closely I started to try to machine them down on my lathe. But then I took a look at the extra pair of drums I had purchased years ago and was pleasantly surprised to see my hub centric adapters fit perfectly. Apparently the previous owner of my car had switched out the original drums for some 63,64 ones. Unfortunately the extra 65 drums are not useable due deep grooves on the shoe contact surfaces which is why I am swapping out the hubs. Thanks for the info Ed!

RivNut Posted April 25, 2020 Share Posted April 25, 2020 There is a company that advertises in the Riview that relines aluminum drums with new steel liners. Link to comment Share on other sites More sharing options...
arnulfo de l.a. Posted April 25, 2020 Author Share Posted April 25, 2020 If its J&G Brake Drum Relining in McHenry IL. , their rate is $550 per drum. A bit much for me. There is also a forum member, MOBILEPARTS, that say he has some for sale. Fortunately the 63,64 drums my car came with still have some life left in them.

RivNut Posted April 25, 2020 Share Posted April 25, 2020 Where do you live? You might be able to find someone closer. Also, 90 fin drums will work. You don't need drums from a just a 65. Link to comment Share on other sites More sharing options...
arnulfo de l.a. Posted April 25, 2020 Author Share Posted April 25, 2020 I live in Los Angeles Ed. When the need arises I will consider the 90 fin as a second option . Link to comment Share on other sites More sharing options...
