Mate, thanks for pictures.
I stand to be corrected, but I don't think those mirrors are made for a R33 as they just don't line up. Although you can sand it down and fit but it just wouldn't look flush. As you can see, not just the edges don't fit, the base also look a bit out of place. I suggest either you go to a special fabricator to get it done properly or look at getting ones that fit flush.
I see what you mean through the pics...just don't fit.
