My Gas N pipes line up very nice as far as level. The right side is a very even 2.5" from the outer frame rail. The left tapers back to 1.75" from tthe outer rail. If the right didn't fit so well I would be tempted to try moving the motor. Is it time to get a wedge for the left or is it ok as is? The body isn't on yet so I can't go by that now.
