2009 transit door lock assy

[swcomms]

Hi, we are currently putting a new door onto a 2009 transit t350 and need some help assembling the new door lock, when the old lock was removed various bits "pinged" off and spread far and wide!, we are having trouble seeing how the spring fits under the new plastic clip on the shaft, is there a website with exploded views anywhere??? I have tried my local ford commercial dealer who was friendly and did his best but was unable to help, thanks
