Vitamin C
From MoparWiki
Vitamin C Orange was one of the Plymouth High Impact colors in the early 70s. More 1970 Plymouth Superbirds were painted Vitamin C Orange than any other color. The same color was referred to as Go Mango in Dodge Speak.
Vitamin C is also the name of a fairly famous 63 Plymouth Belvedere post car that ran Super Stock in the 60s through 80s in the upper mid-west. It now belongs to Dave Schultz, who runs it in the NMCA Championship Series in the NSS Class.
