What is the lightest (from the factory configuration) 5.0L Mustang? Looking at Carpoint, which has '88-'95 Mustangs (as well as my SVT Recognition Guide), it would appear that the 1992 LX 5.0L 5 speed coupe with no AC/cassette player/cruise control and manual windows/locks would be the lightest (MSN lists it at 3010 lbs but doesn't specify whether that's with or without options or how much gas). But I don't have any official or even semi-official info about the 79-87 5.0L Mustangs. I'm guessing that a no options '79 Mustang base model coupe might be lighter.
Still with stock wheels, hood, K member, and a six point roll bar.
I weighed it before I sold it, and it weighed 2860... Go figure
