I've been following headliner threads for a year or so and finally ended up doing it. Just as easy as it looks, takes a bit of time to make it look professional. All in all it was about $80. $40 at the fabric store, $40 at Lowe's.

Materials, not pictured is a 4x8ft piece of rigid foam insulation 1" thick

I used the roll on bedliner a few years ago and did the recessed part of the t tops. I sanded the top with 180 grit and acetone to clean it.

Time to finish the job

Finished product, a section of fabric 4x5ft will be enough to cover the middle and rear sections, I would go 7ft if you plan on doing the front. I didn't buy enough the first time, and after seeing what they had to offer at the fabric store, I might go back and get some fake leather or something a little more high end looking for the fronts. And its actually cheaper than the headliner material.

I used 3M spray adhesive to attach the material to the board, let it sit for 20 seconds before stretching the fabric over it. I used this loctite double sided tape to secure the boards to the roof, they state a 3" section can hold 90 lbs on a vertical hold, but that seems a little outrageous. We'll see how it holds up to the heat.

I would use some cardboard and make a template of the top before cutting the foam board and headliner material. I eye balled it and its not as clean as I would've liked. You can use the 1"thick insulation for the front, but you'll have to knock out a slide section for the clips. I would use 1/2" if you have the option.

Here are some pictures of the notched out panels for the front. Also a while back I got some of that closed cell neoprene another guy was talking about and used that on the side.
