Part number for exterior mirror glass?

[Fred_M1010]

My mirror glass fell off, so I'm in need of a new one.
I looked at Rockauto, but they list a sh*tload of different mirrors for my truck...!?
Does anyone know which of them is the correct one?
I need an electric one for the left side.
I measured it to be about 8.6" x 6", so I thought the correct part was DORMAN Part # 51102, since that seemed to be the closest match...

But then I googled it and found that was for older trucks....
Any ideas?

Edit: while I'm at it, I might as well ask about part numbers for front wheel studs as well.
They had even more choices there

Thanks in advance!

As for wheel studs, the OE size is Dorman PN 610-210. A common upgrade is 610-283, it's 9/16" diameter versus 1/2" diameter, longer and stronger. Of course you'd have to get all 9/16" lug nuts, but it's a good upgrade, especially if you run aluminum wheels, I bought 32 used ones in very good condition off ebay for $20. Beats the $2-$3 a piece at the parts store I may or may not have a spare mirror, if need be, you can have it. I will have to check...

I went to oreillys and got one for a 73-87 chevy and it's damn near identical

Thanks, that would be great!
