The 88 L/D 7200# 3/4 ton rotors are 6 lug. They use the same inner and outer bearing as the 71/72 or HD 73-87 which is A3 for outer and A5 for inner. Dimensions differ as the 88 6 lug are 11 39/64" diameter and 1.285 thick. The 71-87 are 11 55/64" diameter with a thickness of 1.25. They could work --- researched this from what TX Firefighter mentioned. I show a Raybestos p/n 105973 - $58. Allsafe p/n 5973RGS - $30.
