The stock intake points toward the front of the car. Vintage puts a hole in the back engine compartment wall and that lets the intake hose attach directly to the throttle body. It then runs through it in a gentle arc before re-entering the engine compartment through another hole.
JPS uses a 180 degree fitting bolted onto the throttle body to point the inlet toward the rear of the car. The JPS solution is less efficient from an air-flow point of view (some of the 180* fitting available have sharp angles at the welds) and it looks a little cobbled up, but it cuts way down on assembly labor.

It is my observation that one can simply turn the intake manifold 180 degrees (clockwise or counter, doesn't matter!) and it will bolt right up pointing the throttle body in the opposite direction of stock. The fuel lines are then wrong then but no biggie. The real trouble is you now have to figure out where else to mount the alternator. Also not too big a deal though, particularly if the AC isn't going to be used.
They also sell a wedge-shaped spacer to allow clearance to the alternator in its stock location.
