This kit is great. Came with everything I needed and is surprisingly comfortable for a set of HD springs. I didn't realize how much sag had gone on since 1966 either. With this kit I gained over 2" in the rear giving my car a slight rake. My car handles better and looks better. If you are debating about new leafs just go for this kit, you won't regret it.
Just got into the Pony game last year and this was one of my first purchases. I installed the 5 Leaf Spring Kit a few months back and I have to say it was easy to install (getting the old rusty one out was another story) and they made a big difference. The stance looks great (not over the top). the ride is like night and day from the original leaf springs I took off. I'm glad I made this purchase and would do it again if I decide to restore another pony. 100% recommended.
