Looks like mostly 3/8-16 stuff that you can get at the hardware store. The lower pulley to balancer is 3/8-24 x 1" I believe. I would just use what you have on your truck or order new in a kit.

My truck currently only has these dampener pulley bolts (3), 2 for the Alternator and 4 for the WP/Fan pulley anything that mounts the brackets to the block/heads... I don't have. If you know where I can get the "sets" left and right that would be awesome, otherwise I'm going to be hanging out at ACE for a few hours😅
The one you listed is I believe only for the driver's side which is definitely a start, thank you. Only major issue I for see is... I have no idea where any of the bolts go *facepalm*

I used '95 5.7 Suburban as a reference, but not seeing a diagram online. There is probably a way online to see a parts diagram but I am not finding it. You may have to sweet-talk your local GM dealer part guy to show it to you on the screen to see where all the bolts go and how long they were.

Did you get the water pump pulley? Any braces? It's all the little things that make these serpentine setups cost more if bought incomplete. You may be better off going to a junkyard or pick-a-part where you can get all the bolts and braces. You will need another p/s pump or at least a pulley anyway (and it requires a proper tool to remove the pulley, a jaw puller just destroys it as you see).

Is the P/S pulley press fit then? I take it it is... Good for longevity... Bad for replacement... Found a rebuild kit for the pump I got yesterday, found a pulley too just haven't gotten it yet. You are right about those braces... What a pain to locate, the guy I bought the brackets off says he doesn't see them in his "pile" either...

If I was in your shoes, I would go to your local pick-a-part (you do show having one in Phoenix) and buy a matched power steering pump with the bracket, A/C bracket, water pump pulley, and crank pulley. 4.3 Blazers/S10 and 4.3/5.0/5.7 Pickups/Suburbans in the 90s are good sources. Camaros and Firebirds too. Corvette is also nice but less likely to find and uses a shortish aluminum water pump that can't add a fan to it (forces you into electric fans). Van ones are not as good I don't think, could be wrong. Take it off yourself so you get all the bolts and braces. You have an alternator core I think and an a/c compressor core so you don't need those. You will need a new water pump from whatever vehicle you use. You probably want to avoid Vortec V8 engines 96 and up. I think you can resell what you have and still come out ahead on trying to piece it together. Good luck.

Yes, the p/s pulley is press fit. You need a special tool to take it off. I have seen people disassemble the pump and leave the shaft and pulley together to rebuild a pump, but if I bought a used pump and it wasn't covered in oil I would just run it. There is likely a difference in the threads on the high pressure hose from your existing pump to that one but maybe the fitting interchanges?

EDIT-A Serpentine setup is nice, but not really necessary. You really only need a crank pulley to use your original pulleys and add a/c. IMHO the CS130 alternator and R4 compressor are not as good as a 12SI alternator that will fit on your existing alternator bracket and add a Sanden a/c compressor with brackets when you go to Vintage Air. R4 compressor brackets won't support a Sanden Compressor but the later 4.3 S10 Blazer ones do have a pad mounted a/c compressor. Not sure it's as good as a Sanden but the Nippendenso version is pretty good. The offshore version is junk.

Copy that. "wait and get the right/good/complete setup". *thumbs up* will do.
