I've seen the ford ones tapped and ground flat. They work, but just don't have the same shape and structure as gm flats. I'm sure the 1/2" cast is fine enough for milder build, but Chevy one is already cast for beef. I'm honestly just cheap as crap. I like effectiveness, effective doesn't have to mean expensive in this scenario.

what size sawzall blades does it take to fit 40's?
