2500 scr Hatch support arm

[twin533]

Hi, I’m new to the forum. And fairly new to cruisers. i just picked up a 2003 SCR 2500. There are a few parts im having a hard time finding. Your help is greatly appreciated.
First is the arm for the round hatch. It’s not there at all. I found 595-eak20rnd which I think will work but if anyone knows for sure please correct me. The threaded insert is missing as well. It looks like some come with it and some do not.
Second. The key ignition is broken. What would be a direct replacement? Removing dash today to see comnectors and match visually.
Third is there supposed to be a stop for the sliding cabin door. I left the key in the door and nearly sheared it off the first time I slid it open. Maybe I’m missing a bump stop? Obvious fix is don’t leave key in door
Fourth my door to the cabin has a crack. Looks like someone stepped on it from top. Is it even possible to find a replacement?

The second; ignition switch is easy, Any inboard switch will do. There is three terminals B, I, S. Battery, ignition, start.

Check out Normont / NMT SystemsNMT Systems. They supplied the original gas lift cylinders on my 2003 2900. I found their OEM sticker under a distributor sticker. I was able to order replacement mounting clips.
