This is actually on the companies 2003 Express Van. 190K miles and still going strong.

If this works, I hope either a partial Kamm or side skirts like on 18 wheelers is next.

The 94 pickup doesn't get driven at stable speeds/loads/on roads enough to get modded much.
A higher thermostat and grill block are about it.

As a build note, I used self drilling sheetrock screws. Took the wife and I less then 20 min.
Version "B" would probably get lath screws. If the sheetrock screws work loose, I'll change them out.
I started with the van on the ground, but the screw gun was about an inch too long. Out came the ramps.
I'll try to get a better pic of the notch cuts when its not so bright as to wash the photo out.
