It took a lot of time and many reminders, but this morning the postman walked in and gave me a package from Powerflex. In it 2 AR bushes that seem to have the distinct Metro features. The cut in the top (Powerflex calls it the bottom) and the desired chamfer:
On the box it still says PF63-205 which is a problem if you order this set and get the old type that has the cut in the side and no chamfer. I'll install them this week, report back about the fit and ask Powerflex how these can be ordered (and the inner lower arm bushes that are wrong) if you want them as well.
