1969 88 Convertible

I believe that the unique (Raised Rib) design of my brake drums on my 69 Delta are not compatible with the Ametican Racing wheels I purchased last year. When the front rims are mounted, they touch the brake drum at the raised rim area closest to the front wheels. I have been meaning to correct this issue better than the interim band-aid approach I took by installing two washers on each lug before mounting wheels. This just allows a minimum clearance but lug nuts should be longer if I continue this approach.
Are replacement drums avail? Are spacers avail to replace washers? All input is appreciated.
Thanks

Notice raised rib area.

Replacement brake drums are N O T available through the "Chineseum" world of today's garbage parts -- and that is a GOOD thing....
I have N.O.S. very- U.S.A made Brake Drums and N.O.S. ++ Asbestos ++ brake shoes for this application, as well!!!

To the OP, if your wheels don't fit without washers then contact the wheel manufacturer and find out what wheel they have that will fit properly. I am not an advocate of wheel spacers or bolt pattern adapters.
