i had to many loosers in and out of my shop.
ready for my drive shaft and its no where to be found. does any one have measurements or part numbers for the yoke or universal?
its a 64 barracuda with a 273 and a over drive a833.
 
Go to mymopar.com and download your years parts book. Look for propeller shaft and you can get the PN and the dimensions

A 66 Valiant or Barracuda driveshaft is what you need. 66 is the 1st year for slip yoke shafts. In 67 they lengthened the wheel base on the Valiant/ Barracuda so that wont work. And Dart has a longer wheelbase than Valiant/Barracuda 63-66 so that wont work. And a side note that all Valiant/Dart wagons share the Valiant wheel base.
 
Until 1965, A-bodies had the "Detroit" ball & trunnion front U-joint bolted to a fixed flange on the automatic transmission. I don't know about the manual transmissions and your overdrive might add a kink. My 1965 C-body has a sliding-yoke output, but still cable-shift input, making it a 1 year-only housing. If yours needs the B&T and you can't source one (one on ebay currently, but pricey), there are posts on customizing a driveshaft using modern parts, with a sliding shaft at the front.
 
a 4x4 shop can make one as they regularly run flanged yokes and splined driveshafts...but I think you need a 'standard' 66 spec as described., I run a later trans but I also run a 8.75 so mine is gonna measure shorter than what you need. IIRC a 72 Duster with a 7.25 comes to mind as a possible doner...any believers?

The extra wheelbase from 67 on was all ahead of the trans crossmember. Engine/trans is in exactly the same place pre- and post-67. So: you can run a 67 or later Plymouth A body driveshaft (except for Dart based Plymouths like the Scamp), so long as the donor car has the same trans and rear end. I.e., 904 to 904, 727 to 727, 7 1/4 rear to 7 1/4 rear, 8 3/4 rear to 8 3/4 rear, etc. Most A body A833 trans used the same size output shaft as a 727, but some of the early ones (and maybe a few later ones) use a 904 size output shaft. You'll need the correct size yoke.

For example, the bellhousing, driveshaft and 8 3/4 rear end in my 65 Barracuda came out of my Mom's old 71 Duster 340 that my brother rolled (he was unhurt). The Duster had an A230 3-speed manual, which was the same length as the 69 A body four speed in my 65 Barracuda, but the output shaft was 904 sized, so I had to swap the front yoke. Otherwise, the 71 Duster 340's driveshaft simply bolted in my 65 without modification.
