Can anyone tell me what are the correct threads for a 1968 Triumph Trophy 650 Sport Petrol/Gas tank. These are the threads for the emblems and the parcel grid. I read that they transitioned from Cycle to UNF in 68 so that's why I asked. Apparently the transition caused some confusion when they switched. So I'm not sure if all the threads in the tank are Cycle or UNF or a combination. The tank had a strange combination of screws in it when I removed them.
