I'd like a metallic, modern product version of 71 (for 1969), Medium Bright Blue (sometimes called LeMans Blue).

Any suggestions for product mfr and #? I've been to local auto paint store and there are dozens upon dozens of blues. (Mr. Lightfoot?)

Just go to the paint store and buy what ever product / brand you prefer. All the major brands mix it. Mine happens to be DuPont BC/CC. I also bought a pint of PPG Acrylic Enamel in Code 71 to paint a tool box.
