Slant Window passenger door lock

[brianpharmd]

I went to unlock the passenger door on my slant window Sunday evening after a day downtown. I put the key in and and turned it. The next thing I know the disk lock mechanism has broken and fallen out of the door latch.

Are there replacement locks for these handles? I see that Bratton's has a door handle/lock (Part 30380). I can't tell if all of the lock mechanism is out or if part of it is still in the cylinder.

Any suggestions/advice on repair/replace would be helpful. This is not a fine points car but I would like it to look period correct. If it can be repaired, is this something I can do or does it take special tools so I should find someone from the parts sticky that may be able to help?

Thanks

Brian
