Hoping to get some help identifying this transfer case - The 1947 - Present Chevrolet & GMC Truck Message Board Network

This T case is in my 1960 Model B GMC 6000. I thought it was a Rockwell, but it seems the case is reversed. This truck is a NAPCO Power Pak conversion truck. Any help I can get is much appreciated!

Looks like a big Timken, type used on military trucks. It should have an ID plate riveted to it somewhere.

This is not the case in my 1963 5500 B and my 1966 C80 is a Rockwell 223, not sure what you have there, napco must have opted for something bigger than Rockwell 223 on this truck.

Peanutbutter, It was actually a photo of one of your rigs that inspired me to take a closer look. I noticed how far down the T case hangs on mine and wondered why I didn't see that on yours. I am beginning to wonder if this T case is Caterpillar or something. The old military 6x6 folks can't seem to ID it either.

I have seen similar looking cases but can't remember where and in what, I'll start looking for info.

That's a Timken-Detroit casting mark on it:

Thank you Bob B! Half the battle is won now. I appreciate the reply!

Found it, Rockwell T226. They get Huuuge money for these things, now for some googling!
