The phone number for Pat Martin is 614-519-9935. He can do chrome moly or mild steel, I would imagine he could weld up a prefab kit but he bends all his stuff in house for a super tight fit, and I am sure it would be cheaper in the long run getting something custom fit for your car. Hes got great pricing and great customer service, I could not of asked for a better all around finished product from him. He races as a profession so he travels alot when the season starts and his shop is always busy so you may want to call asap.
Also Will (614streets) is a good reference for pats work as well, hes the one who sent me to him.
