Drive Pin Size for Hayward SP0410X Slide Valve?

After having to punch that pin out for the umpteenth time to replace that little o-ring in the bonnet, I've decided I'd like to replace it with a stainless steel cotter pin. Any recommendations for a size to install?
3/32"x3/4", 1/8"x3/4"? I'd like to have the correct size on hand before I tear it apart again. :)

Thanks!

I'm not finding a good size comparison to convert. @JamesW might know. But i Have to ask ..... have you considered just converting to a multiport so you'll have the waste and recirculate options?
