You are kidding me, right?
IIRC...
1LE 3rd gen were either 305 5 -speed or 350 auto, Corvette brakes (which are amazing brakes), aluminum driveshaft, crankshaft, sway bars...just a bunch of cool stuff to have.
1LE 4th gen's were ram air.
They were both lighter cars, so that's why they didn't have AC...91-92 were the 1 LE's to get. And actually I think the B4C's had AC, but I could be wrong.
So whatever crack you're smoking...
