69 Dart exhaust tip and hanger questions

When I posted last night I didn't have the hangers in my hand, just observations from early when I glanced at them. Looks like the rubber is molded with the slot on one side and you just have to punch the backside of the rubber out. I will get some correct mounting hardware and just bottom the L bracket out in the hanger and see if the tips look correct for placement. I am installing Pypes exhaust and will post some pictures on how it fits. Tailpipes are my biggest worry.
