my 74 charger B Body came with the "saddle" motor mount style for a 318. Im putting in a 1972 413 wedge block that has a very different mount style, more of a 3 point mount to the block without the saddle style mount to the frame. has anyone come across a conversion kit to help with this? I dont really want to grind off the saddle mount from the frame so a 413 wedge conversion kit would be very handy. sorry for not having the right terminology for things. Thanks!
