I'm getting ready to swap a V-10 and 4R100 into my 1999 F-250 LD and I'm trying to figure out how much shorter my rear drive shaft needs to be; does anyone know the length of the driveshaft in a 99-03 F150 or 250LD with transmission code E and an extended cab/6.5 foot bed or a single cab 8 foot bed.

Thanks!

 

If no one knows, would someone with a 4R100, an extended cab/6.5 foot bed or a single cab 8 foot bed, and 4x4 be willing to measure their driveshaft for me?
Thanks a lot,
