Hey guys,
my old door locks cylinders were seized so i picked a set (two locks, 2 keys) off the 'net for 25 bucks. just thought i'd share how i did and what i learned. the first lock took about two hours and lots of cursing and doing things the wrong way. the 2nd lock took about 1/2 an hour and went smooth as silk.
so here's what i'd do if i had to do it again:
roll the window down all the way so you can shine a flashlight down in there and you've got more room to work. take the interior door panels off (top and bottom on my '86). pull out the big C-clip that holds the lock onto the door with a pair of angled pliers. then do this:
you can twist that cylinder outside the door so you can get at that jesus clip holding it onto the rod assembly. trying to do this inside the door is INSANITY and i've got the knuckle scrapes to prove it. put the plastic bushing ring on the lock, then place the new lock in the door, making sure the key is in the NEUTRAL position on the cylinder and pointing straight up and down. slide the big C-clip onto the cylinder from inside the door. then put the small clip on that holds the rod assembly. this can be a little tricky 'cuz it's small, but it wasn't bad the 2nd time around and was actually easier than trying to do it outside the door, as twisting the lock back into the door on the rod and getting it positioned right was a pain in the butt.
new locks are nice and shiny, and turn great. i can finally lock my car and get back in it!
