What is it? If it helps, the truck it came out of had manual locking hubs on the front.

not gonna swear to it but kinda looks like a
203,these guys here will tell you for sure though.

203-----and with the locking hubs on the front, it probably has a 'part time kit' in it.

Big J · 11-12-2007, 11:45 AM

Should I stick with this x-case or search for a 205? I'm building this truck for a driver. Probably won't see 4x4 much.

rcflyer1234 · 11-12-2007, 11:51 AM

I would go with a 205 if it is just going to be a driver.

Big J · 11-12-2007, 02:00 PM

I have a 205 on the 4spd thats in my blazer now. Can I use it?

rcflyer1234 · 11-12-2007, 02:33 PM

I dont know why not.

**jamie72** · 11-12-2007, 02:49 PM

no wrong splines.. needs to be an auto 205

**CUSTOM/10** · 11-12-2007, 05:32 PM

If the 205 is from a standard and you want to put it behind a th350 you'll need to replace the 205's in-put shaft and the adpt that goes between the trany & t/c. Or you could buy an special adapter from Advanced Adapters Inc. that will work with the two different splines. (Yes the splines are different.)

I thought you were planing on using the 205 with the 4 speed that is why I said I dont know why not.

I'd use the NP205...Then you won't have any driveline issues (since the truck had a 205 originally) than you probably will with the 203.

Big J · 11-13-2007, 08:37 PM

Thanks for all the help fellas. I'm gonna stick with the
4spd and 205 for now.
