WTB: nose piece for 915 gearbox

I am looking for a nose cone piece for a 73 915 gearbox with a mechanical speedo fitting. I think the part number is 915.301.301 but the the casting number is definitely 915.301.301.0R.

after trying for years to try to fix a small and persistent oil leak where the gear selector shaft enters the box i have decided to get another nose cone and either use it as is or sleeve it with a factory replacement sleeve that is available - but i did not wnat to do it to my current nose cone in case it does not work and becomes worse :)

I may be able to help you Hugh... I have a dig tomorrow.

thanks John
