I used Moog bushings back in I think 1991 or so on a truck. That was the last time I used Moog stuff and didn't really pay much attention. So I'm not sure who makes them for Moog. Regardless, Moog made what I consider OEM quality stuff. 30 years ago may have been a different story, though. If Harris is on the Moog parts, then it's just as good as using GM stuff. Some of the aftermarket replacement part vendors actually made parts for the auto companies and may still do.I have found that a lot of the Moog bushings come out of the box with "HARRIS" on them. It looks like the Moog's are made by the same vendor.
What are waffle bushings ? Thanks for all the info alsoGM liked to use the Harris brand, but the Moog works just as well, IMO. Depending on usages, some bushings were different part numbers and likely was from different durometers. For example, the 84-87 VIN 9 Olds cars used a different part number (per the parts info) on the 8.5 rear end upper ears than any other bushing. Can't see there's much of a difference. But nobody's been able to explain that. It also could be a phantom part number, i.e., where they wanted to use a certain part number in that application, but for some reason it didn't happen.
The biggest thing you have to watch out for is those waffle bushings. Stay away from them, or if you have them installed, get rid of them. They're too flimsy. If you can find some, maybe buy those F41/1LE bushings for the F-body. They'll fit, but they're SUPPOSEDLY a higher durometer than the standard bushings and they're solid like the OG G-body bushings.
