See if you can find someone locally that has recently resprayed a car the same color and has kept the formula, even better if they can put some spare paint on a flat sample coupon to compare with your car and/or park the cars together or put a painted piece of one car against the other.  The base colour on a coupon will not be shiny or have the same flake lay when dry so will still look a little different...

There maybe a paint repair place / supplier that has a photospectrometer type gadget for paint matching and you can remove & use something like the gas filler cap to get a sample pot made. The local paint supplier was able to eye match a non-metallic paint for my EJ Holden and when I sprayed the bonnet and front nose panels I couldn't see any difference between bonnet and guards.

the problem is not that the local paint suppliers can not convert the formula's  for the  colours
its that the paints now days are completely different products.

Back in the 60`s /70`s the paint  were  nitrocellulose lacquer ( duco )  I don't remember what the base of the metallic paints was at that time.

There is a pretty good site paintref.com that lists cars, OEM codes and shows some pictures of the cars with the similar paint option in the OEM colour, this site will also filter into 'Blue Corvettes' which will list and picture every blue Corvette with OEM codes so you can seee what colours had the same codes but different names.

I have attached as an example the Mulsanne Blue list that shows how the same GM code was called different colours.  Also pictures of the 1972 GM colour charts as mentioned above - don't use these to match paint!  Surprisingly my Mulsanne Blue is very similar to current? Mazda Astron Blue...go figure...but the Duplicolor touch-up pen and touch-up spray was acceptably close to do some out of the way touch-ups.
