What's the difference between the '69 RS, SS, Coupe, Z28.

Theres a lot of differences between all of the models youve listed. Try the search function or www.camaros.org .

Theres a ton of info in each.

Left out the convertible.

In a very brief statement that does NOT include all the info. :

RS is appearance package only, not power options.
SS is the power option with engine upgrade, heavier duty other stuff too.
Z of course is the DZ302 engine and manual tranny with other stuff.
As suggested visit the www.camaros.org site and bring a pot of coffee as there is a ton to read. :)
