In the past I've noticed 1994-97 3.8L owners inquiring about or actually buying a 1993 Mark VIII one piece driveshaft as an upgrade. Little do they know that it won't fit! :zrant:

So I thought it would be a good idea to pass some information along. The complaint from people is they didn't know that the 3.8L 4R70W car has a driveshaft that's 1.20" shorter than the 4.6L car.

To add to this,

4.6 with T45 or SN95 style TR3650 swap 55.5"
4.6 with 05-10 TR3650 swap 63.5"

All measurements are between centerlines of the u-joints
