Hello first post, nice site. Well first off wanted a fox for 20 yrs and spent the majority of my time in the navy trying to find a good platform to get one. The search took me 12 yrs but it is over. I traded my sport bike for the stang of my dreams (working progress dream anyway). Working through the winter here I have been tightening things up and generally giving some TLC. Now I removed the EGR (thermactor tube) and am just looking for the correct plugs/pipe threads/bolt size to put in the holes left in the heads. I have been reading some conflicting information about this mod. Thanks guys. 1989 GT. Now some pics.
