Seat adjustment mechanism

[Lee Craner]

I removed the front seat for reupholstery. Upon reinstalling the seat I find that the cross bars for the fore/aft and up/down mechanisms interfere with each other when in the full aft full forward position. In fact, the up/down bar forces itself under the fore/aft bar.

Here's the bars in the full forward full up position:

32252

Here's the issue, when in the full back full down position:

32253

I can't see any thing that is broken or out of adjustment., but it never did this before I removed the seat. What am I missing? Should these two bars actually cross as shown in the second picture?
