Re: ??? rear end question ????

Somewhere in the middle of the 70 model year GM went to a rearend that was 1.5" wider. So yes there is a difference. 69 and earlier are narrower than 71 and later. The only way to tell on a 70 is to measure.

I think the "narrow" axle is 56 inches backing plate to backing plate. So the wide one would be 57.5 inches.

Somebody correct me if I'm wrong.
