Dropmember (Do you need to go to 2 pc driveline)

I'm getting ready to buy a dropmember for my 72 swb. My question is Do I have to run a 2 pc driveline??? Second How do I tell if I have a small hump or large hump tunnel???

its easier if you use a 2 piece , if you use a one piece you will have to tunnel the cab floor, on the hump if it bolts in its a high hump if it is welded in it is a low hump

Kinda correct.
The high hump helps with the fact that you raise the engine/trans combo when using a Dropmember.
If you use a 2-piece driveline you won't have to tunnel the floor for driveshaft clearance.

Look at this tech article from Nate's website.

Lots of good info and pictures.
What year truck are you installing the Dropmember in?
