Thanks a bunch for your quick reply. The setup was originally from a stock 68 Formula S Barracuda and I plan to install it in my 69 Barracuda so I'm hoping that it will be made to match. With respect to checking the center section for wear, to be honest, I wouldn't know what to look for. Would you be able to point in the direction of some guides/pictures or other resources. How do you tell if it is equipped with L.S.? I'm pretty sure it is a suregrip rearend.
