Found A833

So i found an A833 for sale. I currently have an a230 in my duster and i found this transmission for sale. it has been sitting for years and the owner believes it came off a 68 charger. i was wondering if anyone could help me identify the transmission better, i asked the owner for the serial number on the machined pad but hes not home yet. owner told me it has a 30 spline tailshaft. it is definitely missing quite a bit of parts but i wanted to see how reasonable it is to rebuild it or to at least take it apart to restore the parts and keep/sell the ones i cant use for my Duster. Im also not sure what would be the right price to offer here since the transmission is in rough condition. Any advice is appreciated.

After 1968 B Body trans minus side cover and input shaft and gear. Guessing it is a desirable 308 bearing main case and tailhousing. 1964-65 B Body Hurst shifter mounting plate and 1-2 and 3-4 shift rods. Gears are probably good with gear oil/dust rust preventative, hopefully mainshaft is good. Does he have the side cover assy? The rest, you would have to inspect. Not sure on a fair price, let him give you a price.
