I am still working on this 8-lug D-44 and I have found that I am going to have to replace one of the spindles. I have went to the part stores, and they can't get it. I called the dealership and they said that they can't go back that far(1973). I also went to the junkyard and they won't sell just the spindle they want to sell the whole axle. Will one off of a 1/2 ton D44 work? Would one off of a ford or a chevy be the same? Would one off of a '80-up be the same where maybe the dealership could look it up?
