81 K30 CC/dually - what transfer case?

[K5Chris]

'81 crew cab dually with 350 & 4 spd should have a 203 right?

 

[thatK30guy]

205.

203's final year was '79.

 

[K5Chris]

oh sweet. so it would be a 10 spline if it's behind a 4 spd?

when did the 208 come out?

 

[thatK30guy]

Yes, it will be the 10 spline. 205's in the 1 tons up to '84 are 10 spline. '85 up to '91 are 32 spline.

208's started in '81. All 208's are 32 spline.

 

[K5Chris]

cool thanks

 

[AJMBLAZER]

So the 203 actually ended up in 1 tons?

 

[thatK30guy]
