Hello everybody, I have a Lincoln mark 8 X brace for sale. Don’t need it. No rust and in great shape. Will work on your cougar and thunderbird with some slight work. Also attached are pictures of the lower mounting brackets. You’d need to get something custom made or attach the lower to the SC L braces.

Did the mod on my bird along with the stock V brace and L braces. Will add a picture of my setup for reference. Made a huge difference in structural rigidity.

Any questions just ask, thanks.
