I have a Chrysler road racing red stripe transmission. I´d like to ship it back to the USA. For that I need a certificate of origin. Would you know who built these transmissions originally ?

Is there a Chrysler Classic department that could issue a certificate of origin ?

I'm no expert on Mopar road racing transmission, I did drag race a NP 833 for several seasons in NHRA stock class back in the mid 1970s and was lucky enough to know several of the southern CA Mopar backstock and Super Stock drag racers with 4 speeds also. My point is I'm almost positive the "Red Stripe ratio was for drag racing, nor road racing As far as a cerificate of origin maybe one of the tranny company like Liberty, G force or one of the tranny repair companys like Passion or Brewers can help you get it ship back here properly and legally

4 spd's were made in Syracuse, New York.

If some place modified it, ignore that. Keep it simple.
