Need to get a confirmation on my 1975 transfer case.
Truck is 1975, automatic with a 360 and full time 4wd.
VIN is RW40904
Am I correct that its a NP 203 Transfer case?
Thanks

Given how old these trucks most anything is possible nowadays....

....Crawl under your truck and read the metal tag riveted to the t-case. It'll say "Model" and under or to the right is the model number embossed or etched in the datum box.

 

Yes what he said, and the tag is blue and silver and on the front. Large output aft flange NP 203, small out put aft flange NP 205.

1st pic NP 203 on R, 2nd pic NP 203 on L.

What shift pattern to do you have? 3rd pic 203 on L and 205 on R.

Tag pic is a NP 205. See where it says 205 stamped in the model spot?

 

About 2000 miles away from truck at present moment so I can't look.
Shift pattern is the one on the left.

Thanks

I missed the "full time 4wd" statement, so safe to say you have a NP-203. And if you have a shift pattern of the L/H ****, then yes again NP-203.

Chain drive, sling lube and does NOT use 80/90 gear oil.
