Transfer case-axles questions.

[Phuloi68]

Need some opinions (and pictures) on putting together a chevy 4x4. I have axles from a 79 1/2t, a 85 1/2t and a 81 1/2t. I have a 203 transfer case and a 205 transfer case. I will be using a 81 longbed frame.

I am trying to figure the best combination to use. I will be doing some snowplowing, trailer hauling, and highway driving. I think the ratios on the 79 and 85 axles are 3.73's and the 81 is 3.08's. I am leaning on using the 308's with the 205 t/c coupled to a 350 trans and 350 eng. Any opinions on which to use?

The 205 transfer case is mounted in the 81 frame but I don't think it's original to the truck. The way the crossmember is attached to the frame doesn't seem correct. Can anyone send pictures of a np205 correctly mounted on the right crossmember so I can see what's missing?

thanks and keep on trucking.
