Trans to engine bolt size

[VGVIP]

Hi.
I have a early 70's LA small block that I am going to mount to an engine stand tomorrow.
Can someone please tell me what size bolts and thread I need to get. (I'll figure out the length.)
Thanks
Steve

Pretty sure their 3/8-16 tpi.
But wait till a few more chime in

the original bolts are infact 3/8 (the heads are 9/16) I'm sure Moparhead has the right thread pitch listed

3/8 16 x 1.25 or 1.5" can't remember which
