Mad Vette

I am installing new FlowMaster mufflers on my 71 but I can’t find a good picture of just how they should be positioned. The assembly manual dose not have a very clear diagram nor dose the Chevrolet chassis repair manual. I have tried looking thru old Corvette mags but again little or no views from the back of the car down low. I just want to make sure I am installing them with at the correct angel. If any one has a picture of the mufflers installed on your car I would love to see it. It would really help me out. :)
