Transmission to engine bolt sizes?

I don't have the engine here yet but I want to get the bolts needed to mount the engine to an engine stand. It is a 2007 5.3 truck engine. I did search and found the list with bolts but couldn't find any that said bellhousing?

How deep are those bolt holes in the engine?

Thanks
Mark

I believe they are 10MMx1.5MM and something like 40MM long. I'd double check the length though. I just bought a few and don't recall the length. I hope this helps SOME.

I will have to get longer anyway because of the engine stand but the thread size is what I needed. I don't want to get too long and bottom them out in the block does anyone know how deep the holes/thread is?

Thank you

If they are too long just buy some washers to space them out...
