Bolt size for O-320 lord mounts

I don't know if this is on the plans but I can't seem to find it. What size bolts do I need for the rubber lord mounts for a dynofocal mount for an O320 on my RV4? I know Vans sells a kit but I am trying to get them in Canada to avoid customs etc. I know they are AN7 and drilled, just don't know the length. Thank you.

Good idea, since I just bought $5k worth of engine parts from them!
