Dear Welder Series…
Hello I’m looking to put a mustang two style front suspension in a project 1966 Fairlane, what info do I need to get to you to order a close kit? Thank you

Dear Chris…
The stock track width for a 1966 Fairlane is 58″, Chris.  Our 58″ Mustang II kit (shown here)

refers to an approximate dimension from rotor wheel mounting face to face.  The brakes and wheels you choose will alter that dimension, usually making the track width wider.  I’d suggest you measure your existing tire tread center-to-center dimension using the wheels and tires you plan to run. Decide if you would like a track width slightly wider than 58″ (then order a 58″ kit) or slightly narrower (then order a 56″ kit).

Thanks for looking at Welder Series parts.
