Default 86 Window Stopper Broken

I'm about halfway through upgrading the ribbon regulator on my 86 to a scissor but ran into an issue while adjusting the glass so that it goes up/down evenly.

The window seems to go up about 1/4 inch too far so that the top front corner presses into the weather stripping too soon and prevents the door from closing without breaking the glass. After much fidgeting with the adjustors inside the door, I realized the rubber bar inside is loose and bends against the stopper when the window goes all the way up. (Pic of the part attached - far right)

Most of the threads I've seen are for late models with the plastic stopper. Is an 86 supposed to have the plastic stopper and guide later models have? If not, any suggestions on how to fix/replace the loose rubber part, as it doesn't seem to be removable.

I found a few parts here, 2nd and 3rd row for 84-96.

Is this an upgrade for the 86' or is something that came on later models? Thank you.

I put a later model scissor regulator into my 86. The photo is an example of the mounts in the window itself, which is 86 original.

Pretty sure 84-86 was ribbon and 87 on was scissor lift.
