Dear TT-Skylark, Jim, Loren, Walt, Mark, and mid-60s Buick caregivers,
Sorry I didn't offer this answer when this question was first posed, but it has been crazy in California with all the bad weather.
I don't think I have seen a floor shift dash, what do people do with the auto Trans window?
If you want to get a bit more fancy, you can make a plate that fits into the lower dash bezel and hides the window completely. I should have a template on my computer somewhere, but I couldn't find it in the few minutes I searched tonight. If you are interested I can make a more careful search later. I glued my template to a piece of aluminum with rubber cement like this:
I put a hole in the center so I could route the tach cables, unless you go with a tach on the column obviously skip that step. I then first cut it to shape:
Then I did the usual process of filing and testing the fit until it fit nicely. I then mounted it into the lower bezel of the dash like this:
Here is what it looks like from the back:
Here is the speedometer instrument assembly partially completed:
Finally, here is the completely dash to see the overall effect:
It is definitely more effort, but it does make the dash look like it was intended not to have a transmission shift window at that location.
Food for thought!
