Does anyone know if a Thunderform box from a 97/98 will fit a '96? I called MTX and they could not tell me. What would it take to modify one ? Seems to be no aftermarket setups for the 96 extended cab. I personally have a 98 Kota but a girlfriend of mine has a 96 and heard my Thunderform sub setup and now wants one for hers ..lol (both are extended cabs). Custum building one for her is kind of out of the question for now, as work has me slammed. Anyone modify one to make one work? Thanks for any ides. Wrench.
