About to fall-tank straps gone!

[TRC911]

Hey guys, I looked on google and the search bar and couldn't find any related topics

I noticed that my 84 custom deluxes gas tank has been hanging really low. I decided to drop the plastic cover and was shocked at what I have found

I just pulled the plastic cover off, I didn't even need to turn a wrench. The straps appear to be totally gone.

I was wondering if anybody has had the same issue as this? It is a first for me, I believe I will have to remove the bed right?

The truck is from Ottawa canada, and was brought to the states in the late 90s. Hence the rust.

I am at a loss, and have a tight budget so any tips and advice would be greatly appreciated-
