WD 45 pto housing question

[KS 640]

What is the size of the stud bolts used to attach the housing to the power tube, and the size of nut used for a WD 45?

Nuts are 3/8 fine thread. 9/16 open end wrench. You may have to back off the nuts a little bit at a time as the pto box lowers. Just curious, why are you removing this?

Several years ago had to replace a bearing and reline the brakes and its now leaking oil around the pto assembly. Noticed one of the bolts is
stripped and needs replaced.

The nuts are a double tall type NF nut, not just a regular NF nut.
