Any time, Grant.
I made some unexpected progress this evening

Before turning to more radical methods, I decided to try the punch and hammer again. After 10 minutes of pounding one retaining ring started moving

Another 30 minutes of pounding the other, and it came out too

Sunday morning I did soak it in WD40 - perhaps it eventually penetrated all the way. Regardless, both wheel bearings are out, Dedion cleaned up and painted. As one of the pictures show we welded on reinforcement for the swaybar mount.
I was lucky that it came with the spherical bushing.
Although it is still unlikely I will make next weekend's race, I will continue to plug away. Perhaps I'll make it...
