Reaqr end change
I have a 1977 Drag car, in the last year I have broke 3 rear end yokes . I am looking to change the rear end to a Ford 9" or a 12 bolt. My question is does anybody no of a company the makes a kit for the corvette. People tell me to back half the car but that will be big bucks.

Before you make such a big change, what particular yokes are you breaking? Maybe you just need to step up to some serious HD flanged yokes. And, you are aware that a properly built 12-bolt IRS conversion can handle 1000+ HP, no? If you feel you simply must change to a live axle, Autofab has a 4-link kit for Corvettes...

How much power are you making and what are your 60' times and 1/4 ET?
That autofab kit is really nice and will stand up to any abuse with the proper rear installed, but, it could be overkill for your application.

Those are some serious 60ft times 
Not all HD yokes are the same. Try contacting Mike Dyer (tracdogg2) forum member or call him 214-717-8379 He builds the super 12 bolt diffs and knows which HD yokes hold up better as they are not all the same.
Out of curiousity are you running a Drag Vette kit also?
What kind of HD half shafts and u-joints are you running? Surprised one of those have not broke first. I have seen here on the forum a guy actually twist a half shaft at the drag strip.
