I have decided to fit the braces in the centre [center] of the post and peg all the way through as the car port will be open,so walls or cladding do not apply.
I am looking at 6"x 2.5" braces curved and 30"x 30" from the corner of the post if you can visulise it,the height up to the wall beam is 8ft,do you think this size of brace will look in scale.
