Your best bet would be a junkyard. Go find a sunroof-less 1g and cut its roof off. If you have the equipment, weld it in yourself or pay someone to do it. Either way, it'll be more hassle free than trying to get a fiber glass roof.

Honestly since you were talking about light, try finding a buddy that will let you borrow his 2G for a couple hours and order some carbon fiber sheets and the activator. Then, just stretch the carbon fiber over his roof and you can keep it tight by closing the doors on it, and just apply the resin. Do a couple layers and you should be fine, then cut it to shape and rivit it in place. Shouldn't cost you more then $80 for everything, carbon fiber sheets are cheap on eBay.

Here you go, 38" x 60" sheet of carbon fiber cloth for $45 shipped, all you need is the resin and your good to go. If you want go ahead and get 2 sheets to make it stronger but that should be good enough. For noise, because it is going to make a lot of noise, find a way to fit the stock headliner and then fill it with expanding foam. Should make it more rigid and reduce noise.

This is a much larger project that you realize. You will need to either make a mold, or as several others have mentioned you could use another car if you have a friend or fellow dsmer that will let you use their car as a mold. Make sure you wax the mold or car roof several times so it will release.

It will take multiple layers of fiberglass or carbon fiber for this project. If I remember right for maximum strength you will also want to cut the material on the bias. You will also want to sandwich a thin piece of foam between your fabric (fiberglass or carbon fiber) for least weight and maximum strength.

Also to cut down on weight and minimize the use of epoxy you can lay down a piece of 3 mil plastic (heavy garbage bag) and put your fabric on the plastic, mix up your epoxy and spread it around the fabric, lay another piece of plastic on the epoxied material and squeegee out any excess epoxy. You then take off the top plastic and place it on your mold. Rinse and Repeat.

Styrofoam Sheets are found at Home Depot.

When I shipped my Tranny I used these sheets for packing material. These sheets are 48" x 24" x 1.5" thick. They sell them larger than that as well. The sheets I bought were about $5 each. They weigh next to nothing even at that size and they are industrial type.

I have a 96 Eclipse RS in the garage at my moms house, it died a long time ago. I can cut the top of and send it to you for free, just pay for the shipping. I have to get that car out of there to make room for my new baby. Working on cars in a garage FTW.
