My old one is scratched so I thought I’d get a new one. Just found out there are metal and plastic reproductions. I think I’m putting too much thought in this but I’m not sure which to buy. I would think metal is better but if the original is plastic, should I stick with that? Anyone have any thoughts?
What year is your car? 1968's originally came with the plastic fiber optic trim plate, 69-71 Corvettes came with the pot metal plate. The plastic trim plate was just one more of the thousand different one year only parts found on 68 Corvettes.
Use chemical paint stripper to remove all paint; wash and dry part; paint ALL of it with satin black paint; after about 10 minutes, use cloth dampened with lacquer thinner to wipe paint from lettering and ridges. Alternative is to use X-acto knife to scrape paint from raised areas; DO NOT WIPE OFF SHAVINGS. Allow to dry overnight, then remove shavings. Easy to do and you keep the original part.
P.S. If you just paint over the part as-is or you just touch-up the scratches, the part will look BAD. The only cost is the paint stripper; you need the satin black paint and lacquer thinner for all the other paint repairs you will do in the future.
If originality matters to you then your car should have the metal fiber optic plate, but I'm pretty sure the plates are identical except for the material, and interchangeable. The plastic 68 plate is about $5 less than the 69-71 plate, if price is a consideration.
This is just a guess, but I assume GM switched to metal because they were likely experiencing breakage installing them while threading speed nuts onto the plates plastic studs?
I agree with 7T1vette though, that they are easy enough to strip and repaint, that it probably doesn't pay to replace it.

When I redid my 69, I cleaned off all of the old paint and then painted it and then used a Q-tip dipped in Acetone to clean off all of the letters and chrome edges. If you screw it up the first time you can just clean it off and try it again. Once you get the hang of it, it isn't too difficult.
When I prime, I carefully (but not thoroughly) rub most of it off of letters, or trim that can not be taped, using either a rigid piece of plastic (think of like cutting a strip off of a credit card), or a piece of polishing cloth (think 8000 or higher grit sandpaper) wrapped around a flat head screwdriver tip. Do the same after the satin has set up. Not trying to be too thorough. After sitting about a week, paint is better cured so I can go back at it and really get to all of the edges well by using a careful hand and a razor blade with a light touch.
Re-read post #6. You can wipe the paint off the chrome areas with lacquer thinner and soft cloth BEFORE the paint hardens; or you can shave it off with an X-acto knife blade while it is somewhat soft. Either way works well. Much better than masking or sanding it off later.
The original 68 headlamp fiber optic plate was very flat and had a squared off separator ridge between the left optics and the right optics. So if the reproduction ones are accurate, they are not as nice looking as the later issued metal ones. Their divider ridge is rounded.
I changed mine to metal from GM many years ago. Lou.
My original was metal and I I opted for a metal version on the new one. Some information I came across said the 69 had plastic. I haven’t researched if that’s true or not but I just prefer metal over plastic.
I researched all of the 1968 interior changes from actual cars, in the day. There were many changes. The change to metal fiber optic headlamp plates was in middle 1968 for 68 cars. Lou.
