I found the Petty Blue paint!

It appears that 340 three speed manual cars are more common than would be expected. I know of two dusters locally equipped likewise and have an uncle who has the complete three speed setup out of a totaled out '71 340 demon rust bucket he parted out. I always thought the close ratio a-230 would have been a lot of fun with a set of 4.30-4.56 gears.
