Fuel Tank Filler Neck Grommet

In My 65 Barracuda, I have removed the Gas Tank after pumping out the fuel and... Removed the Rear Shock Absobers for the needed Wiggle room... I did this all by myself ... to replace the filler tube grommet!!!
I dreaded doing it at first, but did not find it that difficult in the end... me being in my 70's by the way !
Yes, lightly grease the filler tube & grommet to reassemble.
And, have some blocks (2 x 4 precut to length) ready to support the tank while putting the tank strap back on... ( if you are by yourself )
