S&W 8 Point Roll Cage Installation

I don't know if it will help but, I had an S&W 8-point roll bar for my 63 330 wagon, & the rear bars landed where the rear seat was. I would contact them & they will tell you exactly where they will sit. I was only an hour or so away from their shop, so I brought my car to them & had them make the rear bars go along the roof line & down the "C" pillars, so you had a hard time seeing the roll bar at all. I had them install it while it was there too. Money well spent & they did a fantastic job. I know you're across the country from them but, they could make up the bars you want & ship them to you. Maybe just send them some measurements of what you need.
