Roy;
I don't think I'd call it the death wobble. It starts at about 60mph and gains in intensity from there. I didn't push it over 70mph. At that point the shimmy/shaking is disturbing but not what I would consider destructive or bordering on failure.
I'm going to take Bills advice and inspect/replace the wheel bearings and look for tire interference. I'll test drive after that. If the issue persists I'll have to take the whole thing apart and replace all the older parts. Classic Parts offers a suspension rebuild kit, but it's a bit pricey. I don't have the $650 to spend on it right now. I'll have to look at all the components and see if I need all the parts or not.
