can or will rear disc brake set upfrom a 99 blazer bolt on a 93 blazer rear end

 

It might but measure backing plate mounting bolt area to make sure it is the same. Or you could do the easier way just swap rear ends and master cylinder from the 99...

 

i am driving the 99 cant find a rear end so i am trying to make something work

 

Why dont you use the the drum system thats already on the 93 rear end? It should work just fine. Granted its not the same as having discs but if its gotta work that should get ya good. Might have to adapt a line or two but you should be golden otherwise.
