8 1/4 identification

are you sure it has 10 bolts. heres a chart that will show you what they all look like.
I've got that pic and the factory service manuals what is confusing me is that on my cover the bolt pattern is the same top & bottom(if the carrier was out it looks like you could flip the cover over and bolt it on). My appraiser claimed it as an 8.25 as well. I don't have the car out yet to get under it but the pics I have are from when I bought it, I have counted the bolt 3 times and it definetly has 10. The other confusing part is the axle flanges have the holes in the to access the flange bolts that are known to the 7.25 but I can't remember what it looks like behind the axles. The car is an original V-8 car as well so I thought it would be an 8.25 for sure. I apologize for the dumb sounding ?'s but I thought I had it figured out and just ordered the diff bearing kit on Friday planing to get the car out & ready, then I see all these pics & posts that have me 2nd guessing now.
