I took the teeth off the gears with a new engine I wanna beef up my original diff with new guts as cheap as I can and have posi. Naturally I am in Canada...so what do I buy? how much ? can it be bought all parts for 1000$?

 

I recommend a new 28 spline Eaton Posi and a set of 28 spline axles. You can get the axles from a '90 to '92 Camaro or Firebird, or get a new set. A good installation kit with Timken bearings and the super shim set is also recommended. Use quality gears, not a bragan brand. All of this will probably be around $1000 to $1200, but might be different in Canada.

 

agreed w/ big gear head.

You might add a bearing cap support rear diff. cover (has two set screws in the cover) - some people say they can't help, but others like them.

 

The Duragrip is now available for the 7.5 10 bolt. It's a copy of the Eaton Posi and it's about $65 cheaper. The only difference is the clutch material.

 

That sounds exactly of what I was Thinking of I will definitely spend the extra for Eaton.
