Guy called me said he was doing some cleaning and a had a B body 8.75 axle housing I could have no carrier, brakes or axles,I've know what the 64 and older look like have put brakes on one many years ago but if you had a 63 and 68 B body 8.75 bare housing laying side by side it's there a difference? I do know the width but never seen a early one blown apart thanks for any help
