Xbox Has Anyone Here In The Xbox Community Seen The Traction Group Website.

Saw the traction group website from the winning Week 40 screenshot. Has anyone here used the link on the 1938 stock traction group advert in-game? I just did and on their site, they have a project to turn a Class 483 IOW BKL 1938 stock into a BEMU. Does anyone know if the In-game 1938 stock is based on what working 1938 stock unit?
