Not being anything beyond a back yard mechanic all these years please tell me if I am correct...
Purchase a .1000 O.D. piece of Delrin and have it turned down to .930 O.D. to fit within the hub carrier and bore the inside to .875 I.D to match the steel pin.
A machine shop can bore that stuff out????? This is way over my head. I had a tough time finding a shop to press the bearing out.
The 2 green bushings would be best for me If you can get them within 3 weeks. Two of the bushings I have are perfect and un-damaged. If it's an issue to get them please let me know because both Dennis Olthof and Hillbank say they don't make them anymore. Sorry but I'm getting so many confusing answers I don't know which way to turn. .......I wish I could just go to NAPA.
