Quote: I bought a Duster spoiler from Mopar Performance back in the day. I installed it on my '70 Bee. There was a area where the rock shield had a flat area. I had to put a small notch in it to clear a support.
About that time they determined that one of those spoilers would slow a Duster down in the 1/4!
I bought one of those spoilers for my Demon from Direct Coneection back in 1978, still have it. I was going to put it on the car, but you said it will slow it down? I was hoping to direct air up to the radiator. Always something....
