Bunch of questions (AD panel)

[NONHOG]

1st question......... alternate fuel tank for a panel ? seem to me I've heard of
using AD truck tank mounted below ? I'm wondering about this one ?
price is right !...............http://raybuck.com/i-66629-1973-81-c...ank-20gal.html

Never heard of raybuck ?

2nd question..........thinking about how much I want to drive my panel what
other brakes will fit (few mods o.k) besides fifty something non huck.
I'm thinking cheap but better and of course cheap ! Somebody on the HAMB
said something about using big car brakes from the sixties ? I think that was just about the front. Drums are o.k. for now.

3rd question.......... Is the panel frame different from the truck ?
Reason I ask is I wouldn't mind getting a truck frame and starting my upgrades on that. While the panel is still in use as I just read here on another thread.

O.K. I am done, answer any or all, thanks in advance !
