I have a 67 Lemans, I am in process of rebuilding, combining new tech with old. One of the new things I am looking at adding are the seats out of a new GTO, however they are much heavier than the old ones, plus adding dynamat to the interior.
I was thinking about replacing some of the sheet metal with fiberglass like hood, trunklid, and guage cluster. I found two places that make some stuff for these cars.
64-67 GTO/Lemans Parts.
1965-1967 GTO - Hood (Fiberglass) GTO-style | OPGI.com

Was wondering if anyone has used these guys or know of others, also what other things can be done to save some weight, but not affect ride quality, this is going to be a DD sort of car not a race car, so not going crazy.

For their size, '64-'67 A body cars are light. This is due to lack of miles of heavy wiring, computers, sensors, air bags, safety bumpers, crumple zones, and a ton of sound deadener. Big weight saver's are aluminum heads and intake. Fenders/hoods of 'glass will also help. Or, if you are a 300 pound guy, you can leave everything stock and get a 150 pound guy to race the car when that time comes. Lots of options. But at 3400-3800 lbs, these cars aren't real tanks to begin with.

Car is already getting a LS engine, but has anyone used any of the companies making the glass parts and how good of fit are they?

Lighter of course is faster but the swap of an LS saves up to 200+ lbs in motor weight. so a 2004 ls1 is powering a 3725 lb car (gto) drop that same motor into your 67 and its now pushing a car that only weighs 3300 lbs. I have no experience with the fiberglass parts

The fiber glass parts fit, but USUALLY need some work to make them flat...they tend to be a bit wavy and sometimes 'shadow" the re-enforcement ribs........If your metal parts are good, I'd stick with them. If you must use f'glass, try the hood first. IMHO, Eric
