Well, they're Quick Release Hinges to be exact. These look extremely tough. But, before removing my old hinges, I noticed that there's a glue behind the plate that connects to the body. Is this glue put on there to make the door line up? Is it something that I can add to the aftermarket hinges, like a certain kind of silicone? What scares me is cutting the stock hinges off and hanging my tube doors with the pin pulls, but then having my stock doors not line up correctly. If you have any buddies at the Japan factory, or if you know anyone with as much knowledge on our trucks as a factory worker, can you tell me if I'm going to be able to plug and play and just bolt the new aftermarket hinges on without a problem?
