HELP weber 32/36 DFEV carb

I'm looking to put one of these on my chevette. I need to know what cars came factory with these so i can get one a little cheaper.:banghead:

Lots of Fords came with the Holley version (5200 series) as well as some GMs. I'm not sure which would have had the Weber unit.

the chevette has the holley 5200 which is only 180 cfm the weber 32/36 is a direst bolt on and is 350 cfm
