1972 Dart Magnum swap, R46RE Trans

A 904 will fit but you won't have overdrive. Gear Venders unit will give you overdrive and very little modification, so I hear.
True and we have the 904, But this is Germany we LOVE to go STUPID fast on the Autobahn, and 3 gears just is not enough..
I drive the Autobahn every day and I get past at 90mph like I am in reverse going 80mph. There is a reason that the MBZs, BMWs go so fast, they can drive like 150+mph on their way to work every day...

Thank you for all you do for us, Bob
