score! ...& a question

[1969 GMC]

Today was my lucky day. I picked up a divorced NP202 transfer case from an old International medium duty truck for FREE!!

This thing is a beast. All cast iron (no aluminum bearing retainers like the 205), 1410 yokes on the input and outputs, and the best part...a Braden PTO stuck on the side (has an oddball 10 bolt pattern, not the normal 6). Apparently this was used in International trucks through the sixties. I haven't weighed it yet, but its gotta be more than a 205. It's huge!!

Anyway, it shifts smoothly and the yokes spin easily.

However, the PTO makes a grinding sound when you spin the yoke. You can also feel it with your fingers.
Does anyone know where I can get parts for it? Or will I just have to tear it apart and price out individual bearings and seals (hopefully thats it!) ?

I have never heard of Braden PTO's before. Braden PTO winches, yes. I guess it makes sense. here's a pic, I took more but my digicam is starting to crap out and it deleted them.
