I have researched this site and the internet in general and still can not find a difinitive answer for the rear end data tag on my 9"

The Tag Reads
WEV-A 9BC
3.50 8.7 780A

If you can help me out it would be great. So far. I think it is from a 70's truck. End to End it is roughly 61 inches. Obviously it is a 3.50 gearing and I think it is a 8 3/4 gear.

Not sure if I will be able to get any further info than this, but maybe you all can help.

One additional question. SInce this is, I think, a 8 3/4 should I opt for a true 9"? Can I use a 9" gear or do I have to find an 8 3/4?
