Extended Driveshaft Needed Or Not?
 

I have a 95 4runner 4x4 v6 auto. i have just recently put a 3 inch bodly lift on my rig. with the body lift i also put a 3 inch drivetrain lift. this lifts the drivetrain (engine, tranny,xfer case) back to the same spacing underneath the body bucket. So tecnicaly i have alredy extended the length of my drive shafts. im also intending on doing a 3 inch suspension lift, by using a 1.5inch coil spacer with the downey hd 1.5inch lift coils. with that said that will be about a 6 inch lift. and in regards to my driveshaft it will be lengthend as if for a 6 inch suspension lift becaus of the 3 inch drivetrain lift. is anyone farmiliar with the length of the rear drivshaft and if i will have any probalems with the length, with this lift set up? will i need a longer drive shaft or not?
