Hi all, I'm up to the next stage of driveline change and this is the diff.
Is the thunderbird 9" interchangeable which any centre (axle spline pending of course) as I'm going to be changing to a lower rear end ratio for a bit more go.
Thanks Chris.

It is a standard Ford 9"; nothing unusual about it. Your axles will be 28-spline.
