I may be a bit late coming to this! However, I share the predilection for Parcels traffic, and requested a few relevant kits for Christmas. Just starting this one. I agree it seems over-complicated - I am dreading fitting the etched door handles. However, undaunted, I am looking for this red monofilament. No sign of it! I suspect the conversion to Parkside. What diameter is it supposed to be? Many thanks for sharing your experience.
