Custom a/c bracket suggestions for an OBS compressor on an LS motor

Thanks. What belt did you end up using?

The belt I used was a Gates Micro V KO61080. Depending on which small pulleys you use, your belt application may be a shade larger or smaller.

When I was in the junkyard, I pulled a bunch of different pulleys off some GM cars. Not sure which ones I used, but I sized the belt accordingly. This belt size should get you close with the recommended pulleys on the linked website.

Thanks but what do you mean by new style? I will be running all stock truck accessories except for the a/c compressor. Since the compressor will be mounted on a custom bracket, it lines up with the rest of the pulleys and it looks like I would need just one serpentine belt.

He means the a/c compressor that comes with the newer motors.
If you use that compressor you would have to notch the frame. Its why im using that old style one. I didnt want to cut the frame and get new hoses etc.
I just ordered the bracket from ls-brackets myslef
