‘64 Valiant Production Numbers

Hello all,

I have a 64 Valiant Signet, 273, Hurst 4 speed, original color and black vinyl top. It’s show worthy. I have the build sheet from Chrysler I got a few years ago, but I’m trying to find out how many of these were produced that year. Not thinking it was many.
Anyone know how I can get that info?
Thanks.
