A friend is giving me 9" that I can use instead of building the type "O" non posi 2.73 rear that is currently in my car Cutlass. I'm not building a drag car, but I know I can build it cheaper than I can a rear end that is obsolete. My question is: can I use the Olds housing ends sold by the aftermarket rear end builders, so I can use the current rear disk setup that has brackets for Olds rear? They say they are for early Olds rear end, but I'm wondering the bolt pattern is the same as that on my present rear end? Any feedback would be appreciated.

Thanks

 

I got in contact with the manufaturer of the caliper brackets and he said I could used them with some modification....Isn't hotrodding fun?....lol

 

The Olds housing ends that are advertised by the axle companies are for the early 60's Olds rears,which are completely different,different bolt flange pattern.

You can get a housing end that is the same pattern that your O-axle has.The ones that Moser has are #7900.The other companies make their versions as well.

 

Thanks for the feedback Brian. Kore 3 the company that made the brackets told me the the same thing about the 7900. They said I would have to machine them slightly for proper bearing clearance.
