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* |

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).

Re: 71 GMC engine swap-arino
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.

Re: 71 GMC engine swap-arino
No real progress today, went to the salvage yard for some other tinkery stuff like a spring shackle... Waiting on the ARP exhaust manifold bolts and Amazon hasn't sent me a replacement 2604 intake yet... Don't get an intake manifold from Amazon... What a pain.

Re: 71 GMC engine swap-arino
I've always bought stuff like manifolds from local speed shops. Online stores are all about moving product, but if you're standing at the counter looking a person in the eye, things are different. For instance, I bought sport wood steering wheel from LMC It went to caca and cracked right out of warranty. If one can take the part back to the seller and hold up the offending product, especially with potential customers in the room, things get handled much more to one's satisfaction...without, I'll say, going all Karen about it.
