Anyone out there ever had any Thiokol model 4t wheel guides made up for the grousers or does anyone know of anyone who does this? I would appreciate the information. I mean professionally made. I know some have made them themselves out of 1/2 round steel bar but I'm looking for info on anyone that makes new ones or someone that has the ability to make a run of them every once in awhile....anyone else interested in finding someone to do this?
