Marty, it looks like the closest grease seals we have to what you're looking for is the Grease Seal # 010-180-00. This seal has a 1.68" inner diameter, a 2.33" outer diameter, and is sold in a quantity of 1. For the grease cap (which I assume is what you meant by hub cap) you can use the Fulton Grease Cap # F001524 which has a 1.94" outer diameter.
