IMHO, after researching this I do not recommend Eaton 70-72 springs with different ratings per side.
The 73 model made both sides equal. This allowed for better handling tuning with the newer " crowned" roads AND radials. Hence RTS advertising shows up in 73.
Also if you buy new Eatons, select a lower rating than you think, or select a drop spring.

My car came with 14 inch steel rims then i.got formula leaf springs. Can you school us on the stiffness? What's that mean?
