70 Z was posting about having a car with odd options and mentioned manual steering and power brakes.This would have been possible with a car that was ordered for maximum performance and the owner checked off the SS option box figuring it would give him additional equipment above what the Z offered.Since SS camamros in 1970 were only available with power brakes,even a stripped down version destined for use as a race car would still be forced to have them from the factory.
As for SS and Z/28.I owned a 1970 RS/SS Z28.It had all 3 options I dont think the SS acounted for much on the package since All Z's had LT1's,and 12 bolt rears,and better suspention then an SS.The package might have added a bigger radiator or some other option the Z didnt have,as well as some small visual differance.Mine was a factory blue with white stripes 4 speed on black interior car with 3.31 gears.I got it as a roller/ex street race car,and aded a mild 454 and super T10 to the original 33,000 mile mint body.It did have all 3 performance packages,and was factory delivered with manual steering and power brakes.I was just adding some interesting trivia about how his car was optioned the way it was.
