Bolt size for a Briggs and Stratton PTO Clutch

[Demons15]

Looking to see what size bolt I need to replace the PTO clutch on a Briggs and Stratton motor. The bolt I took out had really bad threads. Engine is a 4045A7 type 0211. Any help would be greatly appreciated

0.438-20 UNF

Translation 7/16-20 Will need to be at least a grade 5 or better. You have to figure to length yourself as no info was provided.
