Well you can either build an enclosure in the well or use a simple baffle board and sel up the well as best as possible.
I bult two F-Body's, a 84 Z28 and a 91 GTA and tried both setups and honestly had the best performance using just the baffle board and sealing the inside.
I have a dual 12" carpeted baffle board for that car in my garage if you're interested. I used two Boston Acoustics 12.5LF's with it in my 91 GTA and it worked very nicely.

Interesting - I justc yesterday did a "Slamboard" in the back of an 85 Firebird with a pair of Infinity 10s. We used to build 3-4 a month in the early 90s. As stated above - it really does just as good a job as trying to build a complete enclosure back there. I built a full enclosure in my 84Z28 back in the day and what a PITA for no real sonic return

If you log onto there are sub box dimensions and how to build a box pdf files you can print out and build yourself. They accomodate 2 12" in a box either sealed or ported.

I ran 2 12" Soundstream Granites on a baffle board with a Granite 50.2 for power and hit 129db....and got to use the trunk whenever I wanted
