gmc 3/4 ton hub caps

[683/4farm]

Recently bought some hub caps off a board member oregon 1967 gmc and i have to start by saying thank you to him,with all the no trust and lying and stealing in this world we were making a deal on these caps and was leary on sending a money order but this man had paid his own money for shipping and shipped these caps before i even had the money order and sent a picture of the shipping info receipt for proof,so those of you with doubt there is still good people out there, thank you again ray, now onto the caps, i have a dana 60 in my truck and the rear hubs are making the caps hit by just a hair from fully seating, had anyone had this issue and what did you use to maybe hit these centers out just enough to clear? Thank you all in advance.
