Welcome to the site!
First, do you have a GT or a Cobra? You say GT but you also say 4V which would be the DOHC 4.6 in the Cobra. I only state that so you don't buy wrong parts down the line that are either GT or Cobra specific.
Regardless, check out all the sponsor's of the site here. There's a list of them in the forums list and many have discounts for AFM members. I won't list names so you can make your own decision but I'll say I've had great service from all the sponsors I've used here.
Keep us posted!
As an FYI - I ordered a Spec Stage II for my 96GT with the Steeda Quadrant and firewall adjuster... quality all around...
