Seems like a Mustang 2 type setup is in your future then.
Not sure what kind of budget you want or what your fabrication skill level might be, but it isn't terribly hard to do depending on where you buy from and what level kit you get.

To my mind, this is one of those deals where you shouldn't cheap out. Shop around and ask lots of folks who might've done it or have that unit in their car.
I've never tried one of theirs but Fatman has a good rep and I have a Kugal in mine.
