My window lock broke today and I can't lock my vent window. If any one has a right side vent window for a 64 Bug,please please let me know. Or if you have just the lock piece. It is the kind with the drift pin holding it on. 991-1519 or pm me. I would like to get it as soon as possible so I can lock the window again. Thanks.

See if any of these will work. Only $20 and might get the job done

You have to replace the whole latch depending on what broke . You have to have the latch for a '60-'64.  Late latch's '65-up will not work. You don't have replace the whole dang window. Its harder to replace than the latch.

Just the lock itself broke. It broke where the drift pin goes. I was hoping to find just the lock piece and the spring,lost the spring when the part broke. I just thought it might be easier to find a whole window then just the pieces. I have a call into Rick to see if he has any early doors or just the vent window.

You cannot buy just pieces.  Why tear up a good latch to get pieces.  You are going have to drill out small rivets to replace the latch and will have to do the same to replace the whole vent window plus taking the door panel off to get to the bolts that hold the lower shaft of the  vent window frame to the door.  Your call
