FYI: Driveshaft Lengths

[Rodeo Joe]

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!

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.

MODEL YEARS	ENGINE	TRANSMISSION	DRIVESHAFT LENGTH
94-97	3.8L V6	4R70W	57" driveshaft
94-97	4.6L V8	4R70W	58.20" driveshaft
93-98 MARK VIII	4.6L V8	M5R2	58.20" driveshaft
89-95	3.8L V6	AOD	53.80" driveshaft
89-93	3.8L V6	AOD	57.80" driveshaft
89-93	5.0 V8	AOD	57.80" driveshaft

94-97 3.8L 4R70W 57" driveshaft

94-97 4.6L 4R70W 58.20" driveshaft

93-98 Mark VIII 4R70W 58.20" driveshaft

89-95 3.8L M5R2 53.80" driveshaft

89-93 3.8L AOD 57.80" driveshaft

These specs are from a previous group purchase.

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
