318 Poly Vibration
Next: unbolting the flex plate from the converter to see if I can wiggle the converter around off of center.
I would imagine it would destroy the converter seal, eventually, but no leaks yet.
I'll also see what info I can locate on when the snout size changed, not that my converter has never been changed, but it would be nice to know.
Hopefully I can do this asap, maybe this weekend.
This at least gives me something solid to check, thank you a ton.
