Single stage Concept urethane DCC in Matador Red Code DCC3192 SC (The PPG name for Solar Red) for the '68 code 71634 costs $98 per quart. Here is the tint codes on a quart can.
Base/Clear Deltron 2000 DBC in "Matador Red", Code DBC3192H, here is the tint code on a pint can.
Here is the inside of the trunk lid with a finger swipe each of dbc and dcc smeared on. Okay, not as scientific as mixing with the hardener and spraying out a panel, but it gives an idea as to color match against the original color.
Here are the same samples photochopped so you can't compare the glossy edge, which confuses things.
For the upper dash paint, flat Burgandy 71486 for a 252 code car (Red/Red) in DDL lacquer, the part number is DIA71486. Here is the tint code on the pint can. The shop matched the paint to a dash brought to him and it matched when he finished. Perhaps that is why the label is marked. Cost $42.15/pint.
Lower dash, Regimental Red in DDLSC lacquer cost $57.95 for one pint. Part number is DIA71591SC This is the tint code for one pint. This will need to be sprayed out to see the match because it has flattener. That is the DX265 ingredient on the label.
Lacquer is still available in some parts of the country. I doubt you will find in in California.
