[inkfamous13]

Trying to order some push thru bullets for my stock 16in 8 luggers on my c20. Deep enough to clear hubs in rear but having problems finding out for sure diameter of the push thru caps to order. We were robbed at gun point on black friday and the following week when we had uhaul loaded ready to leave next day. It was broken into and all my tools were stolen. So my diameter gauge. EVERYTHING was jacked so im trying to get this truck going and replacing necessities tool wise while we deal with insurance company. And to boot all my tools were purchased back in 96-00 from mac/ matco /snap on guys wich i got no reciepts and cant find these old tool guys that many years later. So it slow process. Well enough of my boo hoo hoo's just need help of what diameter push thru caps for these wheels. All help is greatly appreciated. Thnx
