help with PTE 50 trim turbo

[spyder_dsm]

Okay guys I have a question for you. I bought a turbo form one of the member here and on the o2 housing of the turbo where the wastegate flap is there is a cut between the flap and the wheel there. Will it effect anything if I was to run an wastegate on the o2 housing or would I have to block that off? look at the picture if you don't get what I'm saying. The one on the right has an uncut housing and the one on the left has a cut between the flap and the wheel. I got the one that has a cut. Please help.. thanks
