Okay well working on the truck trying to put the np 241-c case in.... Is there a diffrence from a np241 and a np241-c... (Mine was out of a 1500 95 sub)/ The inpute shaft for the transfer case is about 1/4 or little more bigger then my out put shaft on my tranny.So seeing what you guys know thanks louis.

Also the couple that done the swap crawl under there if you can and see if it says 241 or 241 c thanks.

the "C" is for chevy IIRC
Looks like they had 2 diffrent ones ones with 32 splines and ones with 27 splines going to go count right now and see whats up... I found a guy on ebay that selling them... Im going to see if he would trade my two cases for one :D

If it came from a 1/2 ton suburban it will be a 27 spline unit.

Like I told you in the PM the 241's from behind a 4l80e will not work with your 4l60e output shaft.

The c is just the model GM used. All the d-drop and p-drop, 27 and 32 spline 241's in GM trucks are 241-C's. Dodge 241's are not C's.

An NP246 is worth a lot more than a boring 241 d-drop 27 spline case. Don't go getting hosed in the name of a little quickness.

This is a NP-241 Transfer case for a drivers side front drive shaft, with 27 teeth on the Female input spline. This case will mate up with a TH350 or the 700R4 / 4L60-E Automatic Transmissions...WITH THE PROPER ADAPTER-Not Included. It came out of a 1989 Half Ton K1500 pick-up, and was yard tested. Our Tag # 002467

This generation NP241-C will fit 1988 to 1994, as it has a round mounting flange for the front drive shaft.


Input Spline: We have run into two different input spline configurations on these cases.



27 spline: The units supplied with a T350 or 700R4 automatic have a 27 spline female input shaft. THIS IS THE LISTED CASE!



32 spline: This is the preferred shaft, as it is the strongest. These came behind Turbo 400 or SM465 transmissions & the 5 speed standards. NOT LISTED IN THIS SALE


So i just called the guy it had a tubro 400 in the 1500 sub, So it was diffrent. I need one with a 700r4.

So that would be a bad trade lol 2 cases for one.
