    to drill a 1/4" hole through it and through the center of the oil
    filter,
    and secure with a 4 inch long 1/4" diameter bolt, that will go
    right through
    both. (Only kidding....I will use a 3/16" diameter bolt so not as
    much oil
    can leak out of the hole in the filter).

         Paul,          Before you mount the filter, just fill it with RTV, then you can
    drill any size hole through it without leaking :-)
