Fuse holder-where can I buy one?

[R22tech]

Looking at my fuse box in the luggage compartment, it appears as if "sections" of the fuse holders can be replaced. I need a section but don't know where to find 'em.

fuse boxes: 10-fuse box 911.612.086.02; there are two numbers for the 3-fuse carriers: 911.612.093.03 and 911.612.093.04 found in an Automotion catalog...about $22 for the three fuse, $65 for the ten fuse. MAX
