Back in the day, I installed many dozens of OEM / Delco pads and never had a problem with them.
The aftermarket pads I've tried are dirty, squeal or both.
The Hawk PC pads dirty the rims within 50 miles of driving, squeal, and have poor grip around town. In fact, I'll give them away to any forum member when I get good old fashion pads.
The stock pads are what are known as D-8's. Delco offers them in two styles. With riveted pads, they are available as AC Delco part number 17D8, and as bonded pads they are part number 14D8. Both type are organic, Delco doesn't offer the D-8 with a semi-metallic lining.
I'd be surprised if Delco still uses the same friction material as they did almost 50 years ago but I'll look at them.
Also suprisingly, it appears that asbestos is not banned in brake or clutch friction material in the US yet. And asbestos was used in many pads/shoes classified as organic.

Reason: spelling
From my little research, it appears that asbestos pads were classified as organic. And although asbestos may not be banned in the US for use in brake pads, it is likely that many manufacturers have switch to non-asbestos materials.
RE: GM part number 18028641
A current eBay add shows photos of a Delco box labeled with both GM part number 18028641 and 17D8. These pads are visibly different than OE in at least that the photo shows no vertical expansion slot in the middle. Also the pad material looks darker than I remember though that may be just a photo issue (or memory issue).
P.S. the ebay ad offers the new set for $27 with shipping if anyone is interested.
I'll check the booths at the NCRS FL meet in a couple weeks to see if any NOOS are available. I'm tired of wasting money on aftermarket pads, and it appears the current Delco and GM pads should fall in that questionable category.
P.S. just to make brake descriptions more clear (though more complicated), "Organic" appears to be commonly used for brake materials whose components are not man-made. "Organic" chemistry however refers to compounds and materials that contain carbon atoms.
