I just finished drilling the new holes for the 5/8" pins. That will NEVER be the fail point now. The drill bit cost 20 bucks!!!! I did get an order for another skid plate, so I will use that money to get a new corded drill with a 1/2" chuck. I used my cordless Hitachi Li-ion 18v drill. It made it through 6 of the 8 holes before the battery died. That is pretty amazing for a cordless drill to drill 5/8" hole through 8gage hardened steel.
