OK. So here's the deal.
I unbolted the flex plate (FP) from the torque converter (TC). The flex plate isn't cracked or broken.
I reattached the FP to the TC at the *exact* locations of the old one.
Sound was 10 times worse.
Here is the video of the noise.
So, because it's so close to the oil pan, and rear main bearing that I had to remove to get to the rear seal when I changed that. I couldn't tell if the noise was from there or the plate.
So I disconnected the FP from the TC to see if the noise changed, went away, or stayed the same. Yes, that's duct tape keeping the TC back. I wasn't sure if it would vibrate forward. As I always say "Safety third".
Much more tinny sound that was definitely coming from the FP. It's hitting something.

Ugh. Fongool!! Not my new starter.
So, since I didn't have this issue with the old plate, I'm going to go with this plate is warped.
I've got the new (re-manned) 6 pad TC coming. Maybe I do need to order a new plate.
Anyone got a source for known "good" plates?
Also, what should the distance be between the flywheel and the starter shelf that my flex plate is hitting? It doesn't seem like it should be hitting it even with the TC disconnected.
The good news is, I can take down a starter in less than 5 minutes now.
