Newbie here. I just purchased a built 37 Ford 'Downs' coupe. I'm trying to determine which Mustang 2 (I've been told it is) IFS kit I have for purposes of buying parts & establishing alignment specs, etc. Hub to hub measurement is 56-1/2", this measurement is from the wheel mating flanges (as I was unable to determine if that's actually where the measurement is taken). Don't see any label plate or Part number stampings. Any tips would be greatly appreciated.
