[MDW8973]

Building a Pro Touring 1970 C-10, Doing Coilovers on rear . Already have the tube a-arms up front with the 2 1/2 drop spindles. Which spring height option should I use?

Depending on what the amount of the drop is in the back and if you want to have a rake. We offer a 1-2 or 3" drop coil.
