I just did my (new to me) 1997 on Friday, total removal and replacement with a reconditioned CDL unit.
I have freed up about 6 LR vehicles now and this one on Friday was in the worst condition yet....the pin at the end of the sliding shaft can be seized in place, remove with heat if necessary and please don't distort or deform the vertical lever or you'll be ages getting that little pin back in place....
Oh yes, any thought of freeing this up with brute force are, in my experience, wishful thinking....
Here is a link to a helpful thread at Rovers North in Vermont....
