Anyone in Houston area(old dealer info)?

Hey guys:

I recently bought another original 1972 Plymouth Valiant which purportedly was sold new here in the south, but obviously wasn't. There is a very old sticker centered on the rear bumper that has the Chrysler pentastar, then "Katy Road" and "Houston, TX' underneath that. Based on which dealers sold what I am assuming that would be Katy Road Chrysler-Plymouth. I found a short reference to it being a new Chrysler flagship store back then, whatever that means. Then, in another discussion forum I saw a reference to "Katy Freeway Chrysler-Plymouth at I-10". Can anyone out that way fill in the blanks about Katy Road Chrysler-Plymouth? Thanks.
