1970 A833 output shaft length

Hi guys

i'm picking up a 70 A833 non-OD 4 speed trans on sunday for my 68 Cuda with 8.75 rear axle. i'm trying to get a driveshaft (Dynotech) built in time for Dream Cruise, and the guy needs the length of the output shaft 930 spline) out of the back of the 833 a body tail.
I'm short on time and couldn't get an answer from the seller so far so I'm asking here, Does anybody know the length of the output shaft?
I am getting a 43.5" center to center 3" diameter driveshaft, with 1350 u joints and 30 spline yoke. I think the driveshaft guy at Dynotech needs that length to make sure the yoke and driveshaft length are all good.

Thx in advance guys
