Thanks JonL and cdplayer.
Since I posted, i relocated my misplaced Haynes (British edition) manual and followed recommendations from JonL and cdplayer. I see that it is easy when you have the key, however my replacement door did not have a key. I did my original door first, just to see how it all went together, then I worked from the inside on the replacement door to free up the latch from thee lock. Now I need to put it all back together in the replacement door. All in all it was a good experience.

Thanks for the help guys!
