Check with the Denysenko family at Moneymaker Racing. They race Fords, but don't hold that against them. Good people who will help you get your set-up right. They've been selling the Calvert stuff for some time now and it wouldn't hurt to check their pricing. I hope to eventually get some from them for my car.
I just bought the complete caltrac system with front and rear shocks from Calvert direct and it was $1023 shipped to me in Colorado. Best price I could find.
