Help Request: Missing Collider on Classic Cockpit [Restoration]

[Deimos Rast]

Greetings!
I am currently working with @Hellbrand to restore some of the works of @CoffeeSE. His works are of exceedingly high quality and they have aged remarkably well (with a few exceptions - see below). This is not a promo thread, so please excuse the lack of details.

The issue at hand is one of the 1.25m cockpits, the [REDACTED], which seems to be missing a collider. At least that is my assumption - I know it has one around the hatch, but when it spawns in the flight scene, it sinks into the ground until it catches on the hatch collider (see pics below). In its present state, kerbals can walk through it.

There is also the issue of a "Hatch Obstructed" error when trying to EVA. It might be related, as I've heard that's caused by having a hatch collider not extending beyond the mesh. Or something (my skills, such as they are, are confined largely to a note pad). There is another cockpit that has a similar issue (although it has fully working colliders).

If anyone has any suggestions or advice, please let me or @Hellbrand know. I should mention these cockpits have fully custom RPM IVAs and it would be a shame if they got sidelined over such a minor issue (I'm assuming people will want to actually leave their cockpits at some point ).

Below is a link to the part files in question (textures, model, config) for the [REDACTED] cockpit.
Thanks!
