And what kind of transfer case should my 87 k10 have? How could I tell? Thanks

The transfer case should have a silver and red circular tag on the back of it, with the type stamped on it. It will either be an NP208 or NP241C. The CK5 forum has a pic, spline count, and a good idea to look at e.bay pics to identify the NV4500...

EDIT: Here's another link to help identify the NV4500...

What year and kind of truck is in the field? If it's a '91 or newer 3/4 or 1 ton, it's probably a NV4500. From what I've seen, the half ton trucks are usually (if not always) a NV3500.

And your t-case is/was an NP208. The 241 wasn't used until '89.

It's only a 1500 but ya never know they might have switched it
