Did the Altman latch install this winter............they are awesome. The door close lie a modern car, tight and quiet while still look stock. The BIG plus......They stay latched !!! While the instructions say they ( latches) will not fix poor fit of the doors........they will allow better flushness if you tinker with the adjustment and position of the striker.
My driver's side I moved the striker in slightly from stock........the door is now flush at the bottom and in at the top slightly.
I did not connect the door lock at this time. In the future plan on the remote activation lock and avoid the key.
There is a good reason the stock latch design was discontinued 50 years ago. My wife fell out of the 50's Chevy pickup when she was kid......in the 50's in a non accident going around a corner.
