Nick, there is one in Texarkana on the Texas side but I don't know where. I will try to find out. My wife grew up in Texarkana and has friends who have husbands that will know.
There is also a Tractor Salvage yard in Linden, Texas just about 25 miles or so south of Texarkana on US 59. To get to Linden take the I-30 by pass off I-30 on the West side of Texarkana. At the intersection of the bypass and US 59 go south (right) on 59. Linden is real small, stop in town and ask for directions and I bet you can find it.
Also, this guy regularly runs things on ebay and in the YT photo ads, monitor these for Texas locations and you will probably find an email address and/or phone number.
