I didn't have to mess with the front boss, nothing goes there. The coil bosses work, you just have to reverse the brackets on the coil. The throttle mounts work fine, a little persuasion is all. I had to bend the brake booster vacuum line a little and make my own mount for the alternator bracket and extend the A/C bracket with 3 washers and a longer bolt.
On another note; when you go to install the injectors, put the small O-ring on the bottom and the big O-ring in the body before sliding the injector sin place or you'll pinch them and bend to top plate when tightening it down.
