Either get a posi carrier that matches your current gear ratio (2 series or 3 series) or a Power Trax locker.

I've got a 12 bolt from a Nova in my 55 and when I bought it, I opened it up hopeing for a posi and a good gear, the gear was a 5.38 and a non posi. oh well, bought it anyway.
Non posi, spiders not welded, no tire squeel around corners and no clutches inside, just a regular carrier, but it was tight and had quite a few shims in it,
put it in and built the motor, went on the Maiden Voyage and low and behold, 110 feet of posi rubber, partly due to the 5.38 and part motor, BUT, Posi?
I was dumbfounded, from an open carrier. opened it up again and sure enough it was just an open carrier. I,ve asked around but all I hear is if you shim them tight enough then it will act like a posi unit,
I still dont understand, I will change the gear soon but the carrier does a heck of a job

Sounds like welded carrier. Old trick to make a poor man's spool. You said the ratio was 5.xx:1 which makes me believe that's exactly what was done.

Look for welds around the spiders.

You can put a Eaton posi in your rear end with the gears you have. All you have to do is swap out the differential.
