M1009 trasmission to engine bolt size?

[thedeliverator]

Hi all,
Just wondering if anyone knows the size of the transmission to engine bolts offhand. I've been trying to find the source of the knocking noise coming from under my M1009, and it probably isn't helping that I'm missing some of those bolts....

Bellhousing bolts should be 3/8-16

I suspect you might have a loose torque converter bolt though....
