[6pack] TR-6 Spin-on oil filter

[wcwellbaum at cox.net]

Long story short--I scored a brand new spin-on adapter for my '75 TR-6 
but the bolt fixing it to the block was missing.  Moss Motors was unable 
to help and I'm hoping on of the listers can tell me
the size of the bolt needed to complete the installation of this 
fixture.  Size of bolt, length, and the thread pitch--please.
