I don't know much about blazer's but I have one I drive and one just for parts and both say they have the posi-trac axles on the glove box.

Re: 71 blazer positraction

No value, leave it out on the curb and I will stop by and pick it up. Do you know the gear ratio 3.08 or 3.73 ?

I bought a pair of axles from a 70 Blazer up North.

Re: 71 blazer positraction

My K5 had one in the rear. I sold the whole axle for a couple hundred IIRC.

Now running a 14 bolt.

The SPID above with the FRONT posi is pretty cool though.

It has a 4 speed in it so I'm assuming 3.73, but I have not confirmed

Re: 71 blazer positraction

front axle posi is much less common than the rear. IMO, they are worth 50% more with the limited slips in them. Figure $400 for them without, $600 with.
