As the final step in this add-on, I searched for and found a first aid "filler" kit that nicely fits into the odd shaped space of the BMW underseat part. The kit comes from BMW without contents, and it is up to the buyer to fill the kit with whatever he/she thinks is needed to provide first aid for cuts and injuries when needed.

I found on line and bought one "Small Trifold with supplies - Red", item/part # 911-91511-111 from Fieldtex Products, Rochester, NY. Telno 585-427-2940, or online at <Fieldtex.com>. The kit is wrapped in a red canvas (therefore flexible enough to fit into the black plastic BMW kit) folder with three zippered net envelopes inside. It is shown on the site at 5 1/2" wide, larger than the 4 3/4" space in the BMW part, but because it is soft and flexible, it can be folded over enough to fit into the BMW part. It fits snugly, ergo no rattles! Price with supplies is $23.75 + tax and shipping.

If you are looking to fill your new underseat first aid kit with the necessary items, take a look at a/o try this kit.

Good luck.
