The eldo have the E brake calipers , and Eldo calipers were at one time the pieces used for conversion kits you could buy. Speed way sells weld on brackets for various gm calipers but the Eldo were supposed to be bolt on. I Think some of the GM axle shafts have to have the end nub turned down to fit into the center hole in the Rotor.
Are you looking to sell these? Im trying to figure out if that is what you are saying.
