Trackmaster Chassis?

Hey guys/gals, I'm kinda new to modifieds and I currently do not know who my chassis builder is. I only had a welded "TMC" on the left rear underslung to go off of. After some research, the only TMC chassis I could find was Trackmaster. However, I couldn't find much about them online. Does anyone have any info about this chassis manufacture? Impala clip, 3 link, square tube car. Thanks!

Looks like Trackmaster had 22 Wins in the 2000 season of UMP... Anyone know what happened to them?
