So I've been having a bear of a time with the motor mounts. I bought 89 Mustang Convertible Motor Mounts for my coupe yet they don't fit. I should clarify that the drivers side doesn't fit - lining up the driver's mount so that it would bolt to the engine makes it so that the stud won't line up. Flipping the mount around so that the stud and guide post are in the right orientation is then 90 degrees off of what is needed to bolt to the engine.

What is the part number/specs of 302 motor mounts that DO work? The manual is of no assistance, as usual.
