Interior question

[CG]

Talking 71 cab here. Im stashing away all the parts for my 71 K10 and Im just trying to make sure I stash the right stuff (weird I know).

Im going with 510 medium blue and a white top. The interior metal will also be all blue. Ive decided on stock black interior (vinyl) because down the line if I decide to get rid of it I feel its a more liked universal color vs if I went with factory blue (which I think looks great btw).

Should the dash board vents be black or blue? I believe the top of the dash should be painted a semi gloss version of the 510 (wrong?). Should the air con ball vents bases be black or blue?

This isn't any sort of 100 percent resto but I wouldn't mind if it matched what the factory would have put in there if a truck was ordered 510 medium blue with black interior.
