[Roadsters] 66 spl inside door latch problems

[Bill Cole]

Hi, I'm trying to figure out why on a 66 spl the outside handle will 
work but the inside one doesn't. To me, it is as if the long arm is not 
moving far enough to release the striker. I used a small mirror and 
checked out inside the door and both ends of the rod are fastened and 
the rod seams to be looser than the passenger side which works fine. I 
know being an spl the left door it gets used more so it is expected to 
be worn more than the right side. It looks like on both doors the arm 
floats but on the drivers side it floats a little to much.
  So is there an adjustment I'm not aware of or possibly a simple fix to 
this problem... last resort.... are replacement parts are needed? 
thanks.... Bill
