Converting to rea disc brakes

I bought a blazer rear end to put in my 54 bel air... i should say i bought 2 since the blazer rear end i bought with the disc breaks was to wide for the factory frame and the frame would sit on the calipers. Now my question is is there another rear end like a camaro or something like that that would have the same bolt pattern for the brackets to line up on a blazer rear? I know its a long shot askin such a ****ific question but id imagine im not the first guy to ever wonder if this exists. Just need something that runs a thinner caliper that will bolt up without having to reinvent the wheel. Ive searched for hours but cant find anything on the subject?? any help is appreciated thanx

 

Did you try Jeg's?

 

Wilwood?

 

try CPP in orange co. just put thier rear disc brake kit on my 56 Chevy w/no problems.they have alot of brake solutions

 

yea they all sell disc conversion kits for blazers but all it dose it make it like the factory setup which dosent work which is why im askin about a possible different alternative. Ill check CPP see if they have something
