ok, so i am looking into getting a new set of rims for my 92 daytona because i just finished my rear disc conversion and it has the special handling rear end in it with the oversized discs, now i need 16 or 17 inch rims to clear the caliper. i am looking to get 16x7 rota slipstreams with a 40mm offset in full polished(they look like bogarts) and i have two different bore sizes to choose from, 67.1 or 73mm. WHICH DO I NEED???
