What size bolts to mount a T80?

[ratled]

I'm working on a motor project and it's been sooo long since I used a T80, what size bolt to mount a T80 to base plate? I want to say 1/4 20 but like I said it's been so long since I used a T80

Also, while I'm at it, what belt size, I really should replace that now

TIA

I think you are right, it's the same size as the head screw, the exploded parts view shows "head & housing Qty-10 "
I use link-belt its like $21 at harbor freight, after I first run it i take up the slack by taking out a link.
I think there are two size's of type A belts one for mounting plate and one for the pump mounting bracket, I think?
