69Lsx6.0

I'm thinking about putting a second generation Camaro/Trans Am 10 bolt with a disc brake set up in my 69 Camaro. I know there a little different in width. Has anyone done this ? I was thinking that the tires may become an issue rubbing against the rear quarters if the width is too wide. If anyone has done this, what offset did you run ? Thanks.

If this question has been asked already then I apologize . I didn't see any threads regarding this.
