Thank you for the reply. I wish I could stumble across one of those! And sorry for the confusion, allow me to clear a few things up.

The truck I have is an 83 gmc with a 454, turbo 400 transmission and a NP205, as it came from the factory. It is a passenger drop.

When I said driver side drop, I was referring to the drivetrain I just purchased from a 91 chevy truck, which is a 454/4L80E and a driver drop transfer case, and I do not know for certain what case it is, but it is the 88-00 body style with IFS so Im pretty sure it is a driver drop.

Yeah the electronics are pricey, but im getting the whole set up cheap enough that I am willing to invest a little in it.

So what I would be looking to do is mate the newly aquired 4L80E to the NP205 that is sitting in my GMC already.
