Can anyone shed some light on the strength of the 2nd gen 10 bolt. I think it has an 8.5" ring gear. Also what is the width of the 3rd gen rear, axle hub to axle hub? Thanks.

 

the 2nd gen used the 8.5 ten bolt correct, it is VERY strong (just a little under the strenth of the 12 bolt many 10 second cars useing them) but it will not fit a 3rd gen as the 2nd gens used leaf springs and the 3rd gen went to a 4 link setup

 

My plan is to re-weld the 3rd gen brackets onto the 2nd gen, along with a setup for the torque arm.

 

My plan is to re-weld the 3rd gen bracketry onto the 2nd gen axle, and setup something for the torque arm. I know the 2nd gen is 55.25" from axle hub to axle hub, so to find out it's the same would be good, narrower, ok, wider, bad, unless differnt wheel offsets are used. Thanks TempesT68.

 

Do you even own a 3rd gen? Look underneath!

 

If you find some practical way to attach the torque arm to the 8.5" 10 bolt housing you could make a lot of money since any GM diff could then be used.

Since you're going to try to attach something to a cast housing I doubt it will work very well or end up costing more than buying an aftermarket 12 bolt or 9".

The 2nd gen diff is also wider than a third gen. Do some measurements before commiting to a diff that you might not be able to use.

Axle to axle a third gen is something close to 61 3/4" wide.

I would measure the dimensions. But at the moment, them being project cars, I don't have the luxery. I even have a 9bolt sitting in the the garage, but I am away so that's not going to work either. I have been scouring the net trying to find the measurements is all. My question is simply this. Why spend $2500 or whatever on a Currie f#rd 9", when you may be able to get the same strength with a $150 initial purchase.

 

Pound for pound (ok kilo for kilo) the 9 bolt is much stronger than the 10 bolt. Previously, parts for the 9 bolt were none existant, but that has changed. I currently offer 9 bolt gear sets from 3.2x to 4.10 and new series 3 posi carriers. Other stuff is on the way
