What are they worth help?

I previously posted this in the brakes section but I am hoping I can get some advise here with a few more viewers.

My original post read: "With the loads of parts that came with my 1968 Dart GTS 383 that I bought, I found these brake drum hubs. Does anyone know what they go to? I cleaned this one up a little."

The response and ID on the drums was: "Original rare factory A-body 8-3/4" 10" brake drums."

I am trying to resurrect a 1968 Dodge Dart GTS 383 4-speed car so if I can sell these and get cash that I can funnel back into my project, it will really help.

Also, on my Body Plate, there was a 4 under the A and nothing under the X indicating a non-posi 3:23.1 rear axle so I am assuming these drums, which I am not sure go on the front or back, did not come on my Dart.

Having said all of that, I would like to post these on eBay but really need a minimum dollar amount so I can set a reasonable reserve.

Any help would be greatly appreciated.

Thanks,
