Which 12 bolt do I have?

[Ed Cannon]

When I bought my car it already had a 12 bolt out of a Chevelle. That was 3 years ago and I forgot what year Chevelle he said. Well I broke my left axle Friday night at test and tune. Does anyone know for sure which years Chevelle is a fit for the G body? I know its a bit wide because my frame is notched and my wheels have 5 1/2" back space. I know I could measure them and just have some made but I would like to know. It may be cheaper to just buy replacement axles if I knew what year to buy. Thanks

'64-'67 Chevelle Axle length is 29 3/4" / Drum to Drum housing width is 60.50".
'68-'72 Chevelle Axle length is 30-1/8" / Drum to Drum housing width is 61.50".
Drum to Drum = Wheel Mounting Surface to WMS.

Some Web Info says 68-72 is 62.50" wide but, I'm pretty sure it's 1" wider than 64-67 not 2"'s.
By the Axle width difference it's only .75" or 3/4".
