'72 Air Dam/Spoiler Installation

[Slammit]

For what it's worth department...

I have not found many posts on front air dam/spoiler installations altho some are installed on these 67-72 trucks (maybe I looked in the wrong places?).

Here is what a 1994 Chevrolet truck (aftermarket) air dam looks like installed. These air dams are the same for several years in the '90's - so it does not have to be 1994 specific. The best point of all is that these aftermarket air dams are only 28 bucks shipped! There is one even cheaper of less quality.
That is cheap for a nice effect!

Pushing the new air dam all the way forward we marked the frame and the air dam for new holes. We drilled one hole in each frame rail, one hole in each fender for the LH/RH outer attach points. (Square cutouts are already in the fenders for use with clipnuts). Then for extra strength you can add small "L" brackets to the angled bumper supports for a total of 6 attach points. Even with 4 points spread equally provides a very sturdy fit. The 'clipnuts' were used for ease of installation and fewer parts, along with larger washers to prevent any cracking under normal conditions. If you want detailed pics of these points let me know. It was super easy with nice visual results.
One more point - the amazing coincidental fit places the outer aft edge of the air dam perfectly in line with the forward edge of the wheel well. See pics ( thought I had a side pic but I don't). It looks like the air dam was made for these trucks!
Hope this is not posted in the wrong area....
