After the targa-top I did for my 4Runner this summer, another fellow here in NC approached me about making him one. Being only a hack backyard fabricator and not accustomed to contracted projects, I was a little hesitant... but after soem discussion, I decided I wanted to try out something different which I might do for myself later anyway. So, I wanted to share the whole buildup here for you guys.
The idea is for a 4Runner fiberglass top to be able to be taken apart nad/or used in pieces, w/ a bikini-style rollback top put over the rear seat sections (I've shown pics of mine before). It essentially wil lcome apart in panels, highlighted in this sketch:

with the backseat winows easily popping off in one piece.
First removed the windows, then got out the saw. Cut it in half, then a sunroof out of the front half:

now's a good time to mention - wow was a dusty nasty mess this makes. Resperator and goggles definitely a good idea.
Note, the corner sections are hollow (about 1/2" space), have to be filled. Here's my hack fill job prior to sanding.

Made sure to hang onto the panel that came out of the roof:
