need driveshaft length for barracuda w A-833

Hi y'all,

I am putting an A body A-833 in my 67 cuda and attaching it to an 8.75 rear. I have a longer driveshaft from a 74 dart with the correct yoke, and U joints.

Can anybody give me the correct length dimension of a stock length A-833 4 speed driveshaft for a 108" wheelbase A body.

A dimension of the drive shaft tube from end to end at the welds would be great.

Thanks
Matt
