These are of a 1974 Model year D44. They came off my completely rebuilt D44 when I sold it. The buyer did not need the calipers. They are in perfect working shape. They are the ones pictured in the D44 8 lug Conversion Article pictured here. They have been ground to allow 15" wheels to fit on the 8 lug setup. Asking $40 obo. Buyer to pay shipping.
