I have no experience with gefracing.com but I do have with Five Star Ford. Its in Az.
FIVE STAR FORD . The guys on the Factory Five Forum use them extensively. Nothing but good comments.
They give ffcobra.com members an additional % off if you say your a member.
Its a full dealership that sells alot of other racing parts too. Try their 800 number.
Im not connected with them in anyway. Just passing on some useful info.
