Probably a NP 208 if it came with a 700r4. I don't think our K5's came with 205s in that year. I have an '86 with a 700r4 and my t-case is the NP 208.

Re: need help identifying my transfer case PLZE
 

the guy told me he scarpped the 700r4 and and transfer case and he got the trans and case out of a older model chevy 4x4 but he forgot what model. the stock shift pattern on the console in the blazer is NOTHING like the shift pattern for the transfercase

What does it look like then? Usually they have a tag saying what it is on the back too, unless it has been taken off.

Re: need help identifying my transfer case PLZE
 

nope chevccked for tags before i bought it. nothing there

Re: need help identifying my transfer case PLZE
 

i checked the speedometer cable is on driver side like always. its got a side panel that 4 bolts hold on going to take it off and look inside see if its chain driven or gear driven

Re: need help identifying my transfer case PLZE
 

If it is cast iron, its a 203 (chain drive) or a 205 (Gear to Gear). This is a picture of a 205. Notice the small round cover with 3 bolts in the middle, its an idler shaft cover, the 203 doesnt have it.

Re: need help identifying my transfer case PLZE
 

i think its a 203 where the idle shaft cover is there a drain plug. so iam going with a 203 iam i right?

Re: need help identifying my transfer case PLZE
 

Most likely. The turbo 350 is more common to have a 203 behind it because it was offered that way for a long time. It was also available with the 205 but is a little harder to find.

Re: need help identifying my transfer case PLZE
 

thx for your help iamma try and look around and get me a 205

Re: need help identifying my transfer case PLZE
 

Watch for 1980 models, every 4x4 had the 205

Re: need help identifying my transfer case PLZE
 

any helpful tips after i get my 205? anything i need to know installing it?

Re: need help identifying my transfer case PLZE
 

try to get the turbo 350 and adapter with it that came with the 205, I am not sure if the output/inputs are the same length or the same spline between the 203/205. Your crossmember is the same but be sure to check out the rear out put on the TC as some were bolt on yokes and some were slip yoke.

ya i found one that was in a 77k10 np 205 with 350 turbo $400
