What do you mean, “modify the rails”?

We have had quite a few questions about installing our Mustang II kit in cars that don’t lend themselves well to a conversion. Sometimes “modifying the frame rails” is necessary. What exactly do we mean by that?

I thought I’d put together some pictures that show a few frames that have been modified to accept a Mustang II crossmember. If you have any questions about your frame or any of our parts, please email or call toll-free: 1-888-648-2150.
