OEM front sway bar sizes

Looking for replacement bushings, I followed the 'does it fit?' recommendations from a website, got to 15/16" bushings. Ordered some.

Having put the cart in front of the horse I then thought, 'I wonder what stock sizes were used?' Went looking on the web, didn't find anything definite. The great idea, 'I should have just measured mine,' came next. I did. It is 13/16" (.812")... I'm just curious about the 13/16" part. Maybe some line person ran out of the 340 size (15/16") and slapped in what was sitting in their parts bin... and should have gone in a 225 car. The car being a '73 and the 340 getting choked to death that year, maybe some injuneer decided that the small bar was good enuf?...

Chrysler engineers were very careful with everything. Mundane cars (read "/6 and 318 cars without HD suspension") in 1973 did not come with front sway bars. See post #2. Your sway bar is most likely original and what a 340 Duster was meant to have.
