Tractor78, there is nowhere to put it between the rails on the 60 - 62 frames except the very back (Where I have a hitch and soon a spare tire)unless you re-route the exhaust and muffler and then you have to figure out that. That is one of the advantages of the "ladder" frame that you have over the "X" frame that we have.
Hey Gazim, don't you have a 60-62 chassis? Where did you put the tank?
