I bought a 2003 FLHTPI with a tour pack/radio box and the previous owner who had used the bike to demo emergency lights took out the lock assembly on the tour pack. The bottom plate is still there but the lock assembly in the lid is missing. The local harley shop tells me they can't help me. Any ideas would be appreciated. I am holding it closed with a wire tie now. Thanks

 

Assuming it is similar to normal tourpaks the missing parts should be easy to get. Ronnies H-D website has the parts microfiche and they can supply what I reckon you need. If your bike is a Police model and your lock is a special, look at Ebay where you will find specialists in Police bikes.
