I will attach some pics of my installation. Remember, these doors are rusty and have been buchered many times. Almost 80 years old now! The door handles work excellent. I bought the handles from speedway, and was a little disapointed that there was no attachment screws or gaskets. I made gaskets from a rubber sanding pad I had lying around. It is a linkage design, with a clamp collar that clamps to the square shaft. I welded an arm to the collar. The tru value hardware store had the joints, one of which looks like a linkage to a carb. I used a 10-32 threaded rod between the joints. Also, there is a spring shown that keeps the latch from vibrating open. Hope you can understand this. I think it will be helpful. Kurt
One more pic. I also purchased the smaller bear claw latches from speedway. Worked real nice. The installation was time consuming for both doors. In the end, some bondo or lead will clean things up. I probably have 20 hours invested. Kurt
