Stock 69 K-20 350 pulley set up

[prg machine]

I have a truck I am assembling from the pieces I pulled off the old/tired out 350 that the K truck came with. It is of course the short pump and has the stock externo regulated alternator. It also has power steering.
I believe the power steering could very well be a back yard add on. Clues are; a second thin stamped pulley with "woolered out" holes in 2 places to match the Chevy 3-bolt mounting. mounted behind the single groove damper pulley. There was a misalignment to the belt running the power steer pump from this added pulley. Also the power steering brackets have had some amateurish looking welding/fab done.

Questions:

I plan on using an internaly regulated alternator and from all of the FAQs on this board I understand that the pulleys are the same for my application. No change needed here from what I can tell. Sound good?

My water pump pulley appears correct and is single row. There is a fan spacer. This should also be okay?

So I guess I need to know if I can purchase the correct Damper pulley for the power steering set up with a short water pump. ??Numbers, sources, pics. are greatly appreciated.

Also same for the pump bracket I would assume.

A couple of close up shots of how the pump and brackets mount with headers would also be appreciated.

Thanks once again for all of your good help.

I was thinking maybe summit for a source? Maybe Brothers or Classic?????
