Thanks!
You can buy the springs through Ford although they are a bit more expensive. I picked these up from Gene Evans Racing in GA (
www.gefracing.com) but they can also be had from Jim at PPI. I paid about $150+shipping whereas they will go for about $185 at the dealer. In any case, they are great springs and with the linear rates (600 & 250), the ride is great!
