Jawbone Tackle Co

To all,
I had purchased a Jawbone Pier combo from Dicks sporting goods so, my youngest son can use it on a 1/2 day saltwater trip. During the trip, he dropped the drag spool "cap" into the water. I have tried to get connected with the company, Jawbone, but apparently it is just a distributor. I checked Amazon as well to no avail.

I just need the cap to get my son back to fishing. I don't really want to buy another reel for the rod or buy another Jawbone pier combo.

I will pay up to 15 bucks for this cap.

Anyone?

or connect me in the right direction?

Thanks
