New here, got me a 66 impala,its a mongloid but it moves. Car was pieced together for the sole purpose of hillbilly burnouts, not by me im trying to put it back on the road. Built 350 paired to TH350(counsel shift). I have no clue what the rear end is from, its a 10 bolt cover, 5x5 lug pattern,mounts for upper stabilizers(not used). Crawled under and noticed drive shaft was cut and welded on the farm with a stick welder, its a mess. My question is what kind of rear axle should i look for in the junk yard that would possibly work without cutting/fabbing a whole lot?
