That chart has been around for a long time and is in serious need of some corrections. The '67 to '69 Camaro, '64 to '67 Chevelle and '68 to '79 Nova rear ends are all exactly the same width at 60 inches. The chart has them all different. Also the '68 to '72 Chevelle and '70 to '81 Camaro rear ends are 61 inches wide, not 62 1/2 like the chart says.
Todd, I am getting a '38 with an '80 Malibu 7.5 axle already in it. Is there any way to increase the strength of the components and add a posi ? It may be easier to modify it than hunt down an 8.5 Nova axle.

Thanks !!
