Be warned, just because SGF is the original OE manufacture does not mean that parts sold or re-boxed as aftermarket meet the OE specifications. I learned that at AC-Delco school years ago. They had two lines, the OE line and the aftermarket line. In some cases the parts were the same in some cases they were slightly modified mostly to make 1 part fit multiple models and reduce the part number count.

I think the best bet is when you can find aftermarket parts with the MB star ground off. But keep in mind the star may be ground off because the part was rejected by MB.

Lol. So basically, no part can be trusted.

Easily said but not so easy to determine what works just fine. That's what these forums are about.

Yes?

I generally go by the parts significance and location. If its difficult to change buy genuine stuff. If its easy to replace and wont kill you go aftermarket.

A flex disk falls in between those areas especially if your not used to the feel of a car with a bad one.

Also remember that just because AC Delco does what they did, There parts were still superior for American cars. So choosing a good reputable name brand is a good idea.
