Cone posi

[Franklin Thomas]

I just saw a listing on Facebook for a Mopar eight and three-quarter cone type posi
Is that the normal thing for a Chrysler?
I have a 1966 Newport
Are these rebuildable
Are there different spines that I need to pay attention to for the axles?
Any help would be helpful
Is this a piece of junk or should I get it?
They want 250 for it with no ring gear

They started using them in the 70's (I don't remember the year)

Here's how to rebuild:

That said, I put one of these in my '65 300L. Same price, better style and brand new.

Has anyone used an aftermarket sure-grip?
