All the major paint manufacturers have loooong since stopped making any lacquer automotive paint system. Finding it in a specific OEM color would be a longshot. I seem to recall at one time that there was a company that had bought out either Dupont or PPG lacquers/toners and were mixing colors but I can't remember who and at this point I would doubt you are going to find anything very easily. Particularly in formulated OEM colors. Maybe black and other simple solid colors but not OEM colors. I would be suspect of the quality of any new lacquer today. In general no one actually sprays it anymore and haven't for years.
The good news is that modern basecoats are easy to spray, even metallics. A modern base sprays similar to lacquers of old, and they are pretty much foolproof, provided you use proper technique. And on the off chance that you get mottling or striping of a metallic color there are blending agents that you can use with the base to eliminate those problems. Plus modern base/clears will outlast a lacquer job by a big margin.
