My FR and RL Door mechs are cactus. I got a second hand set of four from on Ebay out of a VR. Before I call in my rip-off-merchant mates to help me, and drink all my damn beer, i was wondering if there was an easy way of doing it. I'm quite familiar with taking the door apart, but i've never had to fiddle with the locks before. Any help would be much appreciated.
