what's swingin

Hey my name is Mike,
i've been reading the hamb for a little bit.new to posting i'm currently building a 54 belaire . my car came with out a rear end somebody told me that a 78 caddy rear will bolt right in does anybody know?

 

welcome,not to often a rear from another model will "bolt right in".

 

Yeah I know camaro rears bolt right in.And I would do that but i need rear disc. My goal is to build this thing to run in the Carrera Pan Americana where it is "STRONGLY" recomended to run disc all the way around.Any ideas would be helpful.
