We needed a 65-66 GT front coil spring for one of our project cars. The problem was we couldnt find them available anywhere. So we made our own! Now, you can have them for your project too! These springs will give your Mustang a firmer ride than stock, but a softer ride than our 620s. They have been tested against an NOS GT350 spring and a 65-66 NOS GT spring. The only real difference is the black powder coating on our springs!
They are the correct replacements for the 65-66 GT 350s and Mustangs equipped with the GT package!
