?'s about bd a 1994 fullsize

standard cab stock floor 3in do u have to cut any of the floor out

you kind of answered it yourself. stock floor means you don't cut the floor.

You do have to cut it to raise the tranny tunnel.

i havent done a single cab but we did my brothers dually and had to raise the tranny tunnel a little bit and we raised the floor where the tank is in the extra cab.

It should be "stock headroom drop"

yup, gotta raise some at the front of the tranny tunnel, then over the gas tank, but that's pretty much it on a big ass fullsize

S-10's are a different story though, alot more floor work involved
