Hooker Competition Headers on A body 4 speed

COMPETITION DODGE/PLYMOUTH HEADERS

Does anyone know if theres any fitment issues using Hooker Competition Headers (1 5/8") on a 72 Duster with a 360 and a 4 speed? I was looking at the instructions online and they have a diagram for modifying the z bar setup but they dont specify if thats on all models or not. Does anyone have these headers in a Duster, Demon, or Dart with a small block and a 4 speed? Anything required or do they fit witout alterations? I have a cheapo set on now that seem to fit ok, but found a nice set of Ceramic coated Hookers for a good price.
