Ive removed the 7 1/4 rear, my springs, shocks, etc on my 69 charger, the car is a 318 car, when I install the 440 with the dual exhaust, where do the hangers bolt up? are the mounts for the hangers for the single exhaust from the small block correct for the rs for the BB? or do I need to intall different mounts on the the frame/body on both sides? is there a source for these?

Thanks

Duane

ps any pics would help.
