[ihc] Info sought on rear gas tank setups for trucks

[Rocky Lear <rockylear@xxxxxxxxxxxxx>]

Holiday greetings everyone! Can somone give me an explanation of the possible tank setups on a 72 crewcab truck? I have both right and left front fender tanks but I remeber in the past that there were different length tanks used under the cab. I want to see which ones I have.I don't have a tank under the bed. But I would like to add one. Was the rear tank optional and if so, how many gallons does it hold? What is the front capacity? Someone mentioned that some t-alls had 100 gal. capacity. I don't think I need hardly that much but could these trucks be had with the same tank configuration?
