1969 Exhaust manifolds

My soninlaw is using the HIPO exhaust manifolds on his 69 Dart 340 Swinger. Not sure if they are the 69 model or what but he is needing to know if there is a place to buy the stock style head pipes or does he have to have them custom made.From looking there is not much room in there for error and it looks like th ebottom of the driver side manifolds bends toward the front of the car which will require a substantial bend in the head pipe.Anyone running stock manifolds on the 69 and can you give us a lead to purchase the headpipes.

Thanks

Bobby
