Transmission Bolt size

[SammieJ88]

Running into a roadblock here. I started bolting the transmission pan up and had at least half of the bolts in and my kid needed help. Long story short I had the rest of the bolts in a metal bowl and my now ex boyfriend decided to throw out the rest of the bolts, out of spite! Needless to say, I have no idea what size bolts I now need, nor do I have access to a micrometer. The parts store here is not very reliable as they don't know half of what they're looking up. I know the head of the bolt is 10mm.
What is the bolt size/pitch for the 4t65e transmission pan?

M8 1.0 pitch 17mm length (early size) 10mm socket head
M6 1.0 pitch 17mm length (later size) 8mm socket head

20mm length will fit also
Both will fit a stock pan.....

If above doesn't work, why cannt you remove one of the bolts you already installed and take it with you to the store?
