First off I hope I can explain this in print so that it makes sense.
What I've done in the past is took a car that had no windshield. Turned it upside down, took model clay, pushed it into the inside cavity where the windshield should go. Set it in the freezer for a day. Took it out, popped out the clay & put it on my vac u form machine & did a mold.
I hope it works for others as well as it has for me.

i do a similar thing for windows too,
i take an inside mold using air dry clay, push it in to the body till it oozes out the window' then using my finger to smooth it off on the outside of the body so its flush with the window opening then wait for it to harden.
when its dry i take some sand paper and smooth of the surface, pop the clay out of the body ( i do the front and rear window separately so it comes out easier)
then i take the dry clay mould and wrap some cling film round it and then gently press it in to a fresh lump of clay (the cling film stops the two bonding together and sticking, i haven't tried a release agent yet)
i let the clay dry again, then gently separate the two parts and now i have a two part mould!
To form the window i place the two mould halves in an oven for 5-10 min, take them out and stick a sheet of lexan in between the two and shove it back in the oven, i watch as the lexan starts to soften and quickly remove it from the oven and gently put some pressure on the two mould halves (i recomend oven gloves lol) sandwiching the lexan in the middle, wait for it to cool off and let the lexan harden.
i dont have a vacuform so i have to make do with this for now, it works after some practice' if you take your time with the clay part, time consuming but effective!
