Size of bolts for oil pump?

[diggidan]

Hi,
I'm going to mount my oil pump back in the sump but I can't find the size of the bolts anywhere.
I assume its M6 but how long should they be?

(And no I don't have the old bolts. I bought the engine and I got the pump on the side).

Thanks guys!

Don't know about different years I believe Honda used mostly the same design for all of them but my 77 is 6x35mm if I'm remembering correctly and the Hondamatic takes 6x55mm
