I bought this from JEGS for $167, Xenon #3125. Took about 4 hours to put it on, I had already removed the front bumper and half of a finger nail a couple of weeks ago. The instructions were as clear as mud so I thought I might make it simple for the 9/74 to '78 one.

The instructions say remove the body pan? You only need to remove the 2 small 1/4 panels under the headlight buckets.

If you leave the middle skid pan it gives it something to rest on. Though it's not secure and could vibrate I'll end up putting a bolt or screw or something when I drive it again.

Squirt the bolts and nuts a day before you start.

I used the bottom of the turn signals as a reference for measuring down in the middle.

I buggered the holes out a little, a little adjustment before tightening down.

It turned out good, I'm happy with the look for now, fiberglass bumper is next!

Im in the same process, but Im going at it from the other direction. Already fitted the fiberglass bumper and now getting ready to fit the Xeon air dam. Mine came with zero instructions.

I opted for the 240Z model to close up the gap under the bumper a bit. Its been on hold for acouple of months, but Im planning to start shortly so it will be ready for driving in April.
