I recently acquired FoC a UPVC door, frame and glazed side panel, with the intention of installing in my garage as part of plan to make my workshop space lighter and less drafty.
Although I have the glazing units for the side panel the problem is the four side glazing beads are missing and it does not look like I’ll be able to find a replacement.

As the beads will be fitted internally, and only in a garage workshop, cosmetic appearance is not of prime importance so I am currently thinking about making some painted wood bead that will fit snugly with silicone sealant. That’s one option.
The other option I’m considering is using just the door and fitting a separate window next to it.
So to the advice I’m looking for….
I’ve worked out the main “welded” frame is the four outside parts. The central door jamb is inserted between the top and bottom rail and secured with screws. Likewise, the horizontal bar containing the letter box is screwed between the door jamb and the outer right rail. Could I “safely” remove (that is cut off) that right hand panel section at the point indicated by the red arrows? Here, when I say “safely” I mean without effecting the overall integrity of what’s left as a door frame. The whole thing would be installed surrounded by (and screwed to) a CLS timber frame.
