Shortening a rear for the 66 Dart.

When I did my Dart I ordered the tires and wheels centered them up in the wheel housing and measured hub to hub. I gave that info to the guy shortening my rearend. You also need to let them know it's for a early A-body so the can offset the center section properly. He ordered new axles for me so we didn't reuse the old ones. If any thing you would want favor shorter on the width, because you can always add wheel spacers easily if needed. Jayson
