IF you hit the block with your drill bit just put some silicone in the back of the hole just in case it were to seep anything EDIT your drilling the block.. correct.. if so measure the depth of the spare block and the cover so you can drill that far in and follow it up with the bottoming bit Last edited by MR_P_BODY; 04/08/15 11:06 PM.
