I'm planning to replace the stock springs on my 67 XR-7 GT with the 620 lowering springs from Mustangs Unlimited. The question is, can I get just the springs or do I need the whole kit with the insulators and seats?
If the existing parts have many miles on them at all, or are very old, replace them. Spring perches especially. It is so much work and while you have the springs out so much easier that going in again later. New perches are not that much more.
