[Healeys] BJ8 gas tank mat?

[Thomas J. Morrione]

Hi again folks. I'm putting in the gas tank and wonder whether it is
advisable to put some sort of mat (one that doesn't hold moisture and is
thin enough so as not to have to reset the strap attach points on the rear
wall) under it in addition to the large rectangular foam  gasket that Moss
sells for the hole where the drain is. I know the idea is that no water
should be able to get into the boot and the tank will be strapped tight to
the floor; but it seems that some chafing is inevitable without a cushion of
some sort in between. Necessary? Recommended, or not?

Thanks in advance,
Tom
