I got a freebie the other day that might end up on the minivan... bumper off a Pontiac Bonneville SSE... it's too wide, but I think I might be able to section it okay, see a likely point to either lap a seam and bondo it in, or butt join to a T piece that will make a fence to push air over the top. Has two driving light openings that look draggy, but might use those as ram air inlets.
I remember The RoadWarrior..To understand who he was, you have to go back to another time..the world was powered by the black fuel & the desert sprouted great cities..Gone now, swept away..two mighty warrior tribes went to war & touched off a blaze which engulfed them all. Without fuel, they were nothing..thundering machines sputtered & stopped..Only those mobile enough to scavenge, brutal enough to pillage would survive. The gangs took over the highways, ready to wage war for a tank of juice
