More info on Canadian 72 swinger 340s

i am looking for more info on the 72 swinger 340s that were available only in canada......i know a few members here have a few examples but i would like to find out more about the whole program that led to the production of these cars.

i would mainly like to know if they were all swinger specials (LL23) or were some the swinger LH23 code?

were they available with bucket seats? buckets were not supposed to be available on 72 swingers but neither were 340s so were these cars made exception for the engine option only or a group of options.

did these cars have stripes and scoops?

i did a Google search and didnt find much info on these cars.
