Holley accessory brackets

[fillpot]

Guy's been thinking about swapping my truck accessories out for these but had a question,can I use my powersteering pump, alternator,etc with this, I know I would change out the p/s resivor because that is one of my problems being real close to a control arm bolt, any thing else needed, this is a trailblazer ls2 in a 69 Camaro btw. THANKS!
