Thank you for your help. LONGBOX55, I hope you can find a brand and a part number for me. Were you able to find any 7/8 inch lug nuts with a 1/2 thread? The center caps won't fit on the back because the axle sticks out a little too far, I would have to punch out the center. Did your catalog state that the rear will have to be modified or do you know that from experience? It is strange that the front will work without modifying the hole, but the rear will. Are the lug nuts on both trucks a 60 degree taper?
Oldtruck 1946, I was a little confused on the 7/8 inch lugs. Don't I want 9/16 or 14mm lugs?
