Ring gear size for 67 B-GT

["Palmer Family" <amesfolks@snovalley.com>]

I am replacing the ring gear on a 67 B-GT and I need to know how to measure
the size so I can order a new one.  I was told by the owner that there are 2
sizes and I need to know which one.  I have the engine out already.

Please let me know asap!

THANKS
