Air tanks.

Yes, there's 9 other billion posts about this, but i actually did a quick search and couldn't find it..

So anyway, i need some air tanks now, i am looking for like a 9 gallon or something. the ones that are about 32 inches long or so.

i would prefer 8 ports or more.

The ones that AIM (lame) sells that are 9 gallon longs, are those the ones that fit between the frame rails on an s10?
