That's purdy! What diameter shaft does that have? I like the ring.

It is 28 spline unit but I have 31 spline units and eaton units and even true trac units being made.

I am even doing lower cost reconditioned unit for the guys that just need a driver posi instead of everything brand new. Tried to cover all the bases with as much money as I could hang out there for a small business guy.

I had a machine shop do the ring and drill the holes for the units .... As I always say let people do what they do good. I am not a machinist...lol JIm

I am trying to supply these for way less than the SCU .... that is just too much money and these rears deserve to be back on the road...

Is that a Ford 8.8" unit?

It's good that Eaton changed their carrier design.I had a few machined a few years back,and have all the specs to do more.With those I can do 28 or 30 spline.I even did one with 33-spline.I put this in a Vista housing,with the bigger SET 10 axle bearings,and Mark Williams was the only one that could cut me the right axles.It looks pretty ignorant.I did it for myself.
The newer Ford units are nicer too,and now I can put the good Eaton 10-bolt/12-bolt chevy style clutch packs in them.

That's a great price on a unit guys.I might just buy that myself,as sometimes it takes my machinist awhile to get these done for me.
