Cat flap parts - anyone have anything?

Just bought one in very good condition but not glass or any other parts needed to fit other than the top hinges that attach to the door, but not the pin or the hinge holder that fits above the flap inside the truck. Also need one of the guides on the side where the locking mechanism goes through as it only has one. I can see the locking side parts for the bars but I don't even have the bars so may look at gas struts. Be easier to switch between canvas and Station wagon top. Long shot but anyone have anything knocking around or know where I can buy items. Thanks, FFG.

Try Dunsfold, they hold a lot of unobtainium parts.

Or pablanchard I've had a lot of odd bits of them at reasonable prices .
