on3 5.0 fox, motor mounts and clearance
Im installing a newer revision on3 kit in my '89 coupe. Car has never been wrecked and has the stock k member. Motor mounts are new oem ford replacement convertible mounts. The driver header clears the sway bar bracket by a mile but is kinda close to the steering rack boot on that side, passenger side header is resting on the ac line and pressing it down and is also almost touching the frame. I spaced the engine up .400 and got the passenger header off the ac line and the driver header looks pretty good even between steering boot and sway bar bracket. I thought these kits were suppose to fit best with the convertible mounts no?? How much clearance should i have between the passenger header and frame?
