69 Camaro Alternator and Power Steering Brackets

[Unreal]

This subject was a spin-off from a thread about neg battery attachment location, so rather than continue to hijack that one, I thought I'd start a new one.

I know the 1969 b/b alternator bracket set and power steering set were very short lived. I always thought they were unique to 1969. But the discussion in another post got me to thinking. Someone said they observed 69 style brackets on early 70 b/b Chevelles, so the question is:

1. Would extended production 69 Camaro engines (coded Cxx) have 69 style or 70 and later style alt and p/s brackets?

2. Would they be the same for any Chevy b/b (excluding Corvette) ie. would a September 69 (70 model) Impala, for example, use the same brackets as a September 69 (69 model) Camaro?
