Alternative valve stem oil seals for GK76A P/N 09289-04001

[Marsbar]

Hello,

I am currently rebuilding yet another engine but this time i would rather use an alternative valve stem oil seals rather then the OEM ones that are £96 a set.

I have been buying random oil seals from one of our suppliers at work as a logical guess that it might be the correct one. Unfortunately they do not list seals by size so it is becoming quite difficult to source.

here is a list of seals i can get from suppliers:

From the seals i have already tried from there are:
734.08.39
734.08.05
734.08.47

Any help would be appreciated thanks
