I was doing the same thing lately. It's almost impossible to find the one you need. I found one for my application in the UK and it would cost me like $25 for a heim. Almost makes more sense to just buy a new set at that point. The only cheap heims you will find are the ones they use on american roundy round cars.
I found this but I don't know if I would trust it:
