I’ve always used the bell housing bolts that hold the engine and transmission togethe.

They were too short for my engine stand but that's definitely a good idea. The bolts I use are grade 8.8 by the way.

Copy that, if I ever need replacement hardware in Honda thread pitch but different lengths I always find class 12.9 or 8.8 at ace hardware in what I need, maybe if there’s one local to you they might have some.
