I was flushing the coolant in my Massey gc1715 and I lost the bolt that goes on the side of the engine block. My parts book doesn’t have the bolt in it? Any ideas? Any help would be appreciated!

Welcome to the forum.
Are you saying you lost the drain bolt?
I've been digging trying to find parts diagrams and like you, haven't found what you're looking for.
Does the hole look like a normal bolt hole or something more exotic?
I went a little sideways in my searches and thought of block heaters for your tractor thinking they may use the same holes/bolts.
Looks like this is the part # for for a block heater. It mentions a M8x16 Capscrew(339124). That's a pretty standard bolt.

I figured it out. It was a 1/4” NPT. The parts booklets on the newer versions include it. The old ones didn’t for some reason.
