Plan on mocking up the engine on the car, but I need engine brackets. Its a 318 going into a 72 challenger. From the looks of it, these brackets are hard to find. I can only find one aftermarket supplier that may have the set that will work, Schumacher '66-74 B,C,E-Body 273/318 or 340/360 Replacement or Upgrade Kit (mancini racing sells it for them too Engine Conversion and Replacement Kit). Anyone had experience with this particular bracket, does it fit? Id hate to fork out 200$ if they dont work.
