Op stated that the adjusters are all in.
And one side is on the bump the other is about 1/2" up
And he just started to notice.
I agree it is logical to have it be a catastrophic failure, but you don't know till you really dig around
FYI My 67 dart with 323,000 miles has a ton of range left in the adjusters and sits about 1/2 inch from each bump. OEM bars.
