Need stud ref for Volvo Penta GSi 5.7L 1999

[Fab-Miami]

Hey guys,

On my Volvo Penta GSi 5.7L from 1999 (installed on a same Chris Craft) I was trying to adjust the tension of the V belt, the one which goes to the steering pump.

To do that, you have to unscrew two bolds. While doing that, the screw of one of them broke. Rust issue...

I need to change that screw, but despite my searches, I can't find the part number.

Can someone out there give me some help?
(see pictures)





Thanks!

The stud looks like the number 33 on this schema (which is not the right one for my engine).
