transfer case
 

which transfer case is in a 97 chevy 3500 with an nv4500?

should be an np241. Drivers side drop, I want to say 32 spline input but I could be wrong.

anyway to adapt these to a better T-case this is thed third one in 10,000 miles

it does us ea 32 spline fastcr is correct. here is a good link to a little information on them

im surprised your having trouble with one though they tend to normally be great transfer cases

x2. You don't hear of problems with them very often. What problems are you having?

i think one tons have borg warners

The 2500 light duty I have is a 241 my 2500 Hd and 3500 have a different t case in them I don't remember what it is though.

I've read this somewhere although the only 1 ton I've been under (95-98 k3500 srw 6.5/auto) still had a 241 in it. Maybe only dually k3500s have them.

my 94 1 ton single rear wheel doesn't have a 241 nether does my 98 3/4 hd. I think it might be a 271.

i think its the 241. it grinds and wont hold the gear adn will only go in 4 lo. got it out now and getting another tomorrow for $150.
