NP 203 Transfer case help

[MBFW]

I have a 76 Blazer with the 203 in it. (350/350). Transfer case needs a chain. Found one that has the 27 splined input shaft, and fixed rear output, but it doesn't have the cross member mounting bracket that mine uses. How many different versions of the 203 were used, and will the one I've found from a 3/4 ton be adaptable for my vehicle? This is a plow/site vehicle-no plans for road. Thank. MBFW

I know not one thing about the cross members, but welcome to the forum.

This thread may be of some use. I don't recall HR talking about the cross members, but there should be some info as far as to how many varieties of 203s are out there.
