We do have some pucks, they're about 5/8" thick x 2" dia with about a 9/16" hole in them. They're $3.00 each.
Give us a call and we'll get them going, just make sure to say you want a URETHANE puck. We sent some 1" alum body lift pucks to a guy by mistake just recently. They don't have much give to them for a T-case mount!
Thanks
