4L80E 4wd Swap

[66gmcguy]

Hey all. I'm trying to figure out how to do a 4L80E swap in my 1982 K2500. It's currently got a 350/SM465/NP208 combo and I just can't live with the SM465 anymore. I was originally thinking of getting an NV4500 but since this thing is my daily, I'd rather go back to an automatic. Having O/D is a must, and I don't want to use a 700r4 because of sensitive throttle valve adjustment, so a 4L80E is really my only option. I realize that I need a VSS output on the T/case, so ideally, I would get a NP241C from a 91 suburban, but as predicted, those are nearly impossible to find. In fact, the only NP241C that has VSS I've found is a 27 spline output (I need 32) but the guy wants $1000 for it, and it needs a complete rebuild. I did find a guy who's got a NP241C on the back of a SM465 he wants to sell, but it has a cable drive output. Is there any way to convert it to a VSS? Would parts from a newer driver drop NP241 swap into this unit? Or am I SOL until I find the exact transfer case I need? I'm open to any ideas on how to get a good, reliable VSS output for the transmission controller, even if it means converting the NP208 I have, if that's even possible.
