Turbo waste gate

Hi all have got the beast back together Head, water pump, fuel pump ,Injectors, Radiator, Belts ,
Now …. what sort of circlip is on the waste gate of the turbo charger ? I have made an adjustable link . But in the process
Lost the circlip . grrrr Its been a big job started at Christmas. and its just going now fit a few more bits and then off to have it tuned .
I hope it pays off . Exhaust, front mount intercooler , Air bags . just about done

Could you use a bit of tie-wire in the absence of the circlip?

That's my usual "go to" stuff

Yes that is what I have ATM .
I think I removed a fancy clip AND now I cant find it !!! I think the workshop elves may have it .. .

What brand turbo is it?

Factory turbo with a different set of bits inside !!
