1985 D150 SWB 904 to 727 swap, need driveshaft length!!

Pulled a driveshaft from a truck with 727 yesterday and stuck it in truck with a 904 at a pull a part yard. Seemed to fit fine. Anyway, thanks for the help yall.

Found a 92 truck with a roller 360 LA...REALLY tempted to go back and get that engine, lol...
