Are you saying you have the associated style front end??? if you are then yes you can use the rc12l3 turnbuckles for the steering links. also i think the front end may have been different for the older models of the trinity car, the revolver. if i remember right it has two plastic arms like you described, but im not sure if it used turnbuckles or not. could you post a pic? i would be able to tell you when i see it
