Turbo 383 in a A-body Barracuda

Wow!! Hotside is done!! I will have to do a little hammer & dollying to the lower radiator support to straighten out where I rolled the lip. Now I need to figure out how to mount the wastegate. I am going to put it into the merge just below the T6 flange.
Now I have a question,
I am screwed as to where I wanted to put it in the prior pics. Can I 90* off the flange/merge area or does the exhaust have to flow directly into the wastegate?
