Installed the kit on Saturday. Despite the power going out about halfway through the process, I managed to get everything sorted.
Also removed the boots off of the throttle body hose and replaced the clamps with T-bolt clamps.
I managed to get the stainless steel zip ties fairly tight using some needle nose pliers to roll the end of the ties. Probably not as tight as using the zip tie gun would've been, but these rails aren't going anywhere. Used a punch to lock the ties.
In fact, the only rail that wasn't hammered in place with a dead blow mallet was the front passenger side rail (the short one). I can still move it up and down on the TMIC, but not side-to-side. I assume this is normal.
Thanks to BarManBean and SeeeYa for getting this kit to market.
