[Oletrucks] Gas Filler Neck Hole & Rust Damage

[Kent S. Butler]

I am working on replacing the in-cab gas tank in my '56 3100.  Thought it
would be a good time to replace the cracked and worn out filler neck grommet. 
Upon removing the old one, there is rust damage underneath and now a piece of
the lip has broken off.  The damage is about 1/2 inch to the right of the
keyhole (at the bottom) and extends about an inch and a half up.  The good
news is that the damage will be concealed underneath the new ruber grommet.
Looking for any suggestions on how to fix this problem.

Thanks in advance,
