Drive shaft length

[MileHiSS]

When I install my M22 behing my 409, is there a stock drive shaft that should fit, or will I have to have my PG driveshaft modified?

P.G. shaft- front section= 26 53/64 4sp. shaft-front section=24 5/8 measurements are overall length Whack 2 1/4 and you should be there.

Not sure about the length of the larger diamiter yoke needed for the M22 compared to the M20. Maybe the same length, but would need to research.
