[DeTomaso] Mr Fumble fingers has a question about gas tank filler bolts

[Jerry R Knotts]

A bit cold in the garage today, while I was changing the gas tank filler.  I 
now have 3 of the 4 bolts where they are supposed to be but one is between 
the tank and the body.
If some one can tell me what the bolt size is for the bolts with the 10mm 
head, I can find the errant miscreant at a later date.  These little devils 
will do anything to be free.

Thanks in advance,
