Hey Anders,
Is that your car??

Very nicely optioned. I'd like to see more pics if possible and what original parts remain. I'd like to break it down further:
Body Build: 01E (January 5th week)
64-447 NW 2943: '64 2-door Sport Coupe (SS) / Norwood, Ohio / Body sequence #
Trim 713: Black Bucket Seat Interior
Paint 900: Black (Solid) -This is a biggie. I don't believe there were many black cars.
ACC W2L3C: As described above (Tinted Windshield, 4-Spd & Padded Dash)
E: Black painted interior sheet metal (dash, windshield pillars, top and bottom of doors...)
Yes, the 2L is 4-spd and V-8 only. As a note on the option de-code listed: 2P is believed to be the 1st Comfort & Convenience package and not PB Radio. Take a look here:
http://www.corvairkid.com/65-67rpocode.htm a bunch of people worked on this data.
As mentioned, this car should not have a center console even though the assembly manual shows one with a 4-spd shift plate. -Apparently it didn't happen. Does it have the original '721 block/engine and trans? What about the original shifter and floor shift hump? '64 4-spd cars are bit different than '65+. Do you have the rear diff. codes?
