LWB Mid Chassis & Sway bars in NIB Kits

[HKS_TRD]

Ok, so we all know the Turbo Optima Mid Special was loaded with every option house part, but what I am trying to determine is

1. There was the alloy and the fibreglass chassis, which chassis was the Mid Custom and Mid Custom Special equipped with from new
2. Did the Custom Special come with sway bars OOTB, the manual says no but I have heard otherwise so not sure what the story is
