Cant find the right part for powervalve (EC125)

[adde]

Hi, i bough a gasgas ec 125 from 2003 recently and took the powervalve apart because it did not work and found some damage on the powervalves. I been looking for over a week now after a new pair and i just can't find the right parts. I found out too that some old yamahas powervalves can fit too. But i just really wanna get help finding powervalves that will fit.
