thanks did some more research last night late when I finally got home to my desktop, and was about at the same conclusion, didn't know what years to be looking for though, article I found about it on HotRod mentioned late 80's to mid 90's but didn't get any more specific than that. I'll start my search in the 90's then!
It did mention looking for something with no smog equipment, don't know exactly how that narrows my search down, or what to anyway.
I used a 1990 C1500 setup, I got it all cheap as a starting point. It had an air pump, but obviously I didn't mount that, and it was a non a/c truck with the giant dummy pulley in its place. There is an alternate hole to mount the idler pulley on below the A/C and you use a different belt without the air pump mounted. I cut off part of the lower passenger side bracket that you would mount the air pump to, because the metal fuel line from the fuel pump would hit it. Now I am EFI, so eh, might have left it...
Things to remember, all cheap from junkyard.
SHORT water pump, REVERSE rotation pump (I think they look identical, but have different vanes on the impeller) and REVERSE rotation FAN. (I almost missed the fan, remembered at last minute)
I have an odd p/s pulley alignment issue, which could be a couple causes. Probably related to pump/pulley/bracket all coming from different years/engines. The guy I got the setup from didn't have the p/s pump any more.
I have since shimmed everything and seems to be good enough.
I put new tensioner and idler pulleys, added A/C, but never finished it. And I have the A/C delete pulley as a backup. I'll never adjust another v-belt, listen to squeak/slip again, got a MUCH better alternator, everything about it is a win, driving wise.
But yeah, it is not the most attractive setup, but nothing under my hood is, I'm function over form under the paint.
One other issue, which is worse with the cheap plastic tanked aluminum radiator I put on, top hose routing is tricky getting it past/around/over/through the alternator. Even more so depending on top hose outlet location. I bodged up a fan shroud from a 1990s pickup, kept hacking away at it and gut it mounted up in 3 pieces. It isn't pretty either, but DANG, I have tons of airflow now, and my cooling issues have gone.
check out post 8, that is what I got and worked with.
And when I put it on, it was the perfect time to do the JGC P/S swap, and everything matched hose end wise, no adapters, using a newer Camaro pressure hose.
