Bought mine from Eaton and they made it sit up like a 4×4. Had to cut a coil off and it still needs to come down a little more. Everyone i showed this picture to thought either the motor was out or it had stands under it but the engine and trans was in it and nothing under it raising it up.
Not sure, but most of the time the different places sell the same brand of parts, I like Classic only because I live close enough so I can actually look at the part and compare them with my originals before I buy them. Classic has started coming out with some better fitting parts.
had a similar issue with my hood tach on my 69 400. the tach was wired to the ignition. the tach lights were always on whe the car is running. i changed and wired to the lights, no tach unless lights were on. Duh. I wired back to ignition and put new LED bulbs in the tach. it works fine that way for me. Not sure if that helps
