72 gmc door panel color question

[FoodStamp]

I recently bought a new to me passed down barn find, well an out in the woods find. 72 GMC C25 350 3 on the tree long bed all original only missing the a/c compressor. Im going through it and will be trying to get everything cleaned and unfroze to get it drive-able.

I have been reading about 80 some pages back on this forum learning about this body style as im a squarebody guy.

The door panel i removed from the drivers side to do other work matches the color of the body which lists on the SPID as Option No. 518 medium green. The part number on the back of the panel lists as PT#3998019-LH-CAV#4. The back of this panel lists part #'s for each color available which this shows parchment which is defiantly not this color i dont think. These panels are 70s OG style dried out plastic and i was browsing replacements and the medium green which somewhat matches the glove box and the instrument cluster the olive green color. I want to keep it all original style when I do get to the point i restore it.

Only thing i know at the moment is spraying 303 protectant on the old panel to maybe stabilize it and put it back on. The back of the panel is solid probly never been off and retains the same color as the body.

Just curious and thanks for the Help ill try to post pics when i can get them downloaded and posted soon.
