Numbers matching, rolled off the Arlington Texas assembly line in December of 1968. Sold through Brown Pontiac in Amarillo Texas.
Orginally a YS 400, it's now wearling genuine #722 round ports. I still have the #62's and everything needed to put it back 100% showroom stock if I ever decide I want to, including the non-Safe-T-Track 3.23 10-bolt and factory control arms.

I'm the third owner (I think) since new and bought the car with my dad while I was attending college in 1975. The frame off resto began in 1985, but I had to put it on hold shortly into the project. It resumed in June of 2008, finsihed "a couple of weeks ago" --if they're ever really finished.
Car was originally Palladium Silver with black vinyl top, but the owner prior to me had already repainted it metallic blue. Once I made my mind up to ditch the top, it was easy to decide to take the next step and paint it my favorite color.
