Mini-tubbing is a slippery slope. Things that need to be considered i addition to the tubs themselves: -Narrowing the gas tank -Notching (or removing completely) the rear seat for clearance -Rearend suspension changes (for leafspring, offsetting the mounting, think most of the aftermarket 3 & 4 link setups are designed with tubbing in mind) -Narrowing the rearend (you could adjust by using wheel offsets, but to me the deep dish look is part o f the bad @$$ you get with mini-tubbing) -Exhaust modification
I couldn't justify the cost and effort in all this for myself, so I jammed in what fit.
