I doubt seriously if you are going to find any manufacturer here in the States that makes a repop of the Mexican Sprint/Mach 1 graphics.
You might try and see if you can print out the pics, and then contact one of the vinyl graphics companies and see if they can make a set for you...or talk with a local paint shop, someone there may be talented enough to be able to mask it out and paint them on the car when you are ready.
You do know that by making your car something original like that you are going to hear many purist talk bad of you for doing something so sacreligous like that....or more likely, you will get a few of the "I had one just like that when I was younger!" guys coming up to you whenever you take her out for a drive.
I like the idea though, it doesn't really look to hard a job for a painter to pull off for you. Good luck on the search!
