need info on bolt size for rear oil pan longer bolts?
 
I had an oil leak out of the back of the motor and thought it was the rear main so I pulled the trans replaced it, and the leak was still there so I pulled the oil pan changed the gasket and put it back together. Problem is I am missing the two longer bolts that are all the way toward the back of the pan sump (The longer ones toward the inside.) I pulled one of the shorter front bolts and measured it. They were 8mm with a 1.25 thread pitch. Metric bolts are hard to find for some reason in Charleston, SC so I ended up ordering two from the internet that were long enough had to wait a week for them and guess what there not the right size. That is the way stuff goes though. Does anyone happen to know what size they are? I really hate to pull the pan to figure it out and waste another gasket. Thanks guys.

They are M6x1.0x136. I would just get them from the dealer if I was you.

Do not overtorque them. 106 INCH pounds I believe.
