Someone there must at least know where to find the info you need. if not the actual specs
*FourEyedPride.com is dedicated to promoting the 1979-1986 Ford Mustang and Mercury Capri. The intent of the site is to encourage owners of 1979-1986 Mustangs and Capris to preserve their 'Four-Eyed' identity.
