66-75 & 76-77 Suspension Difference?

[Sport69]

In looking at catalogs, there's always a differentation between 66-75 & 76-77 suspension kits. What's the reason for this?

I suspect its the heavy duty rear axle, with a larger housing diameter??? If so, is it just different U-bolts?

Trac bar is different.

The track bar drop mount and pitman arms are different.

like the others said basically nothing different except the trac bar. Springs and shocks will all be the same. with the exception of some early 66's which used a different rear shock mounting.

My '77 has the goofy "Y" drag link assembly. That is one difference. Actually works better on the road but is really vulerable on the trail!
