Hello all, I have a 1978 Chevy Blazer and I would like to know what transfer case I have....I think it is a 205 but I would like to know for sure......The transfer case will not go into gear so I was also wondering if I should rebuild this one or just buy a used one....whatcha think? These forums have answered many questions in the past and it is greatly appreciated.

Oh Yah.....It has a 350 motor and a 3 speed auto transmission, don't know if its a 350 or 400 trans and I have locking hubs and I believe it has 4 high 4 low and 2 low......if that helps...

If you have a 2HI (doubt you meant 2LO), you have the NP205. You can take a peak at it and look up pictures of both the NP203 and NP205 on the internet to see exactly what you have.
