Rear end help (self made posi)

[brickyard69]

I just removed this rearend from my 69 Camaro project to finish the floors.

While out, I am going to convert it to rear disc.

It is a 10 bolt, but it is the stronger 8.5".

When I opened it up, I noticed the previous owner had welded the spider gears together. Can I run this on the street or will I have issues?

The car will be a pro-touring driver with a 383 and a 4 speed.

Also, I am unsure what the gear ratio is. There are 41 teeth on the ring and 9 on the pinion. Any ideas?

How does the wear pattern look? There is about 1/8 to 1/4 inch play when I hold the pionion and turn the ring.

Any help/advice would be appreciated.

Thanks.

That is really more of a poor man's spool than a posi. I personally wouldn't run that anywhere, but that is me. It really boils down to how much power you have and how sticky the tires are. If you hook going around a corner and are making good power, you could break an axle, and have your wheel exit your vehicle.

By the way, brickyard, that ratio is a 4.56:1. You just take the ring and divide it by the pinion. 41/9 is 4.56. And nance has already told you about the welded spider gears, it's definitely not a good idea especially for a street application. Even for the strip its not a good idea.

Thank for the advice.

I am considering buying a Eaton unit with gears and master rebuild kit.

Has anyone rebuilt a rearend in their garage? Is it difficult or should I send it out to a shop?

I have done two at home. with pretty basic tools. The only thing I took out to have done that I could not was the pinion shims. I had to have it pressed on and off several times to get the gear pattern just right.

With a rebiuld kit you will be getting new bearings?
What I did was take the old pinion bearing and hogged it out just enough to allow a slip fit, no pressing. Then I used this as a set up tool to get the shims right. At final assembly, press on the new bearings and recheck pattern, which will likely be right on, and your done!
