my gears went out of my rear in my 63' and instead of digging threw a junk yard and getting gears that may not be good i want to switch the whole rear out .i was thinking of maybe a 94 caprice and just re-weld all the trailing arm mounts from my impalas on to the newer rear,would the rear be to wide?would the spline\yoke match up?what other newer rear-ends will slide up under w\minimum fabrication required?
