Question then remains, if the transmission crossmember and mount are both correct, why is the engine sitting too high? Issue being, that the header tubes hit the frame rail from below. If the trans mount is broken (which is 100% possible looking at the state of the engine mounts :lol: ), wouldn't replacing it push the transmission also higher, making the header clearance issue even worse?
Well, looking back at your post #35, it appears that you have the wrong motor mount brackets. Will you have other problems (like header clearance) if the correct 64-66 V8 brackets drop the motor down? Don't know.
