Thanks, rwd1342.
I will definitely check that one out at Early Classic if I decide to put the tank in the rear. I like that it's got a reinforcement for the back of the frame. Sounds safer. :-)
Right now, I'm more interested in putting a tank beside the drive shaft in a truck with leaf suspension instead of trailing arms, but no one has commented on that. I guess it's never been done or can't be done.
Anyhow, thanks for the great description of your tank setup!
Steve.
