serpentine with smog pump AND Sanden compressor

[gramps77]

Im looking at swapping my 77 over to serpentine but need the smog pump still and would like a Sanden compressor. Ive searched here and haven't found anything regarding Sanden adapting and I THINK an idler pulley can be swapped out easily for the smog pump.

Any help would be appreciated.

I answered part of my question by finally finding this.

You can run the smog pump, use the smog pump delete pulley or just run without it all together depending on what serpentine bracket set you have. Yes vintage air sells a sander bracket kit and I believe holley has a kit as well? Here's my old 74 k5 with a serpentine setup off a. 89 camaro I just ran straight off the ac comp you the crank pulley

Here's the mock up on the stand. I had the smog pump on it here thinking I needed to run it as a dummy. Turns out the bearing was bad and had to pull it Off. I researched google and ended up rerouting the same belt

I planned to buy a GM new serpentine kit withOUT the AC compressor then just get their Sanden adapter to install a Vintage Air kit.

I wouldn't waist the money on a new kit. I had less than 400 in my used junkyard kit and that was with new water pump,belt,fan clutch,p/s pump. Only the alt and ac compressor were used. You can buy them from the u pull it yards for around 125 bucks complete
