Thats a great shot, Probably one of the clearest photos I've seen of a Falcon racing back then. The cars were very developed by 1967/8 the rear guards were flared in order to get the wider rims on and off, I believe they ran 8 inch rims for group5 the front guards were radiused and flared so the wider front tyres would clear, and that's as low as the front of a Falcon could go. The race weight was circa 1150 kg depending on how much fuel the 104 ltr tank had in it.
