I believe the two different rear ends were based on years. Typically shown as 67-70 and 71-72. I can only give you the measurements from the inside of the brake backing plate mounting flanges, my '68 was 57" and the '72 was 58.5". Sorry I don't have the outside, drum to drum mount.

There is no difference if fleet or step side, just the year differences.

Hope that helps.

I measured my 71 suburban yesterday.
I have 1626 mm from outside drum to outside drum, that would be 64 inches.

Doh!!! This is what happens when you get old. You suffer from CRS (Can't Remember $h!t). I was even thinking those numbers did not sound right but you are correct. 57" and 58.5". I corrected my above post. Thanks for the reality check.
