What reamer should I buy to ream tie rod holes the same as a stock dana 30?? The only ones I can find ar 5/8" or 11/16"(5/8" = .625 & 11/16" = .688) The Large end of the opening on the stock knuckle is .645. Is there a special reamer needed or can I just use the 11/16 one and not ream it fully open?
