what is this transfer case? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Here is what is in my rotted frame piece of #@%$ truck (see other post where I am whining and complaining). Is this a 203 transfer case (full time)? This truck looks like it was made up of various parts lying around. I thought it was an 87 body on an earlier frame, say 78 or 79. It has a 14 bolt FF rear, and a dana 44 front axle. I am not sure about the tranny either, but it's definitely not a TH350. The pan looks a lot like the state of Illinois. I may have to part this thing out to get some of my money back. Thanks for your help!

Chucks Chevy truck pages say the fulltime 203 has the speedometer cable exiting on the driver's side... Other than that, it looks like the 203 to me.. I guess the tranny is a TH400 after looking at pan ID pictures. Thank you again guys.

I agree. TH-400 and NP203.

definitely a 203, mine exits on the passenger side as well.

as for Chuck's Chevy Truck Pages, it has been proven several times that they are not a reliable source for accurate information.
