Chevelle rear ends

[big gear head]

I'd like to correct one thing here. The width of the '64 to '67 Chevelle rear end is 60 1/4 inches with drums and the '68 to '72 rear end is 61 1/4 inches with drums. The axle length of the early rear ends is 29 1/8 inches and the later axles are 30 1/8 inches. I don't know how that 62 inch width got started on the internet, but it's everywhere and it's not correct. There is exactly 1 inch overall difference in the early and late Chevelle rear ends.
