yes, I have heard Gremlin drums will add the 4 1/2 bolt circle to you 4" bolt circle car. do not know if that is correct -- but have read it.
I believe those cars are harder to find than Mopars, Lawrence
yeah im finding out that AMC vehicles are very tough to find let alone a brake hub! Oh well I did cross check some part numbers and the use the same bearings as a 10 inch a body drum spindle.
Im just looking at alternatives thats all maybe its something that might work ya never no. but yes it would be easier to go aftermarket or go with the 73 and up stuff.
