Should be a NP205 or 208. I don't think it's old enough for the 203 but I haven't messed with any Blazers that old. For anything K5 related try www.coloradok5.com
I have a perfectly good NP203 that i pulled out of my '76 chevy blazer. I'll sell it to you for $100, but shipping is guna suck cause its cast iron and very heavy.SDSUmudman said:i found out its the np203. Ive been calling around about a rebuild and everyone seems to want 750-1100 to do it. I can get a used one installed with a 6 month warrenty for 600 from GM truck center. Its the all time 4-wheel drive, but i have superwinch hubs on it so that its not always driving all 4 tires. GM truck center also said they could put a 205 in but they also have to put a new driveshaft in which will run me 1500 for the whole thing. I wish i could do that, but i can't afford it.
truck freight!SDSUmudman said:UPS only allows up to 150 pounds is there another way to ship it?
