1967 4spd/8.75 drive shaft length

Hi, I have a 1967 Barracuda that is currently having body and paint work done. When I get it back I will be using a Direct Connection spool type K to shoehorn a 440 and a 23 spline A833 combo in. The 440 is a smidge more HP than factory so either a 7290 or a 1350 yoke will be used. Not sure yet so if anyone has an opinion of that please chime in. I have a 489 cased 3.91 sure grip center section. I will be using MP XHD springs. Does anyone have a close idea on what the length of a drive shaft I will need to use? Thank you for all your helpful insight:)
