I have mine off of a 78 Cadillac DeVille. I got three from a boneyard and pieced one together to make it work. Still going after 8 years. I have it mounted under my battery tray with a one liter vacuum canister in the wheel well. Is a bit noisy on startup until the engine kicks over....and I have but an Isky 280/480 MegaCam in my Charger.
