The best universal air dam I have seen was from the 80's FSJ.
It was hard rubber and would flex enough to easily bolt on most flat bumpers or core supports.
Also had a nice shape that allowed it to maintain shape well.
A friend put one on an eagle back in the day and claimed to pickup 1 mpg.

I put a small air dam on a Fraud I had.
 Home made out of thin aluminum stock. It knocked off 10 degrees in cruise temp!
I was not interested in mpg back then, so I have not idea as to if it helped that at all.

make it from a truck mudflap, and mount it below the radiator
crossmember.  you can cut it to practially brush the ground.  that'll
help cooling and be road hazard safe.

how about a roof-mounted wing?
