I have a 2021 zforce 550 ex and need a cargo box. I foundationen this one on eBay: https://www.ebay.com/itm/174800682947?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20180816085401%26meid%3Debf8e27c943641d08da874257d8c8fb8%26pid%3D100970%26rk%3D1%26rkt%3D15%26sd%3D174800682947%26itm%3D174800682947%26pmt%3D0%26noa%3D1%26pg%3D2380057&_trksid=p2380057.c100970.m5481&_trkparms=pageci%3Aadbbf879-db3c-11eb-8edd-064c772faf3b%7Cparentrq%3A677d995017a0a7b267dce24dffe6a075%7Ciid%3A1

And was wondering if it is compatible with my 550 ex Even though it says zforce 800. Dimensions on the two sxs Are pretty similar.

Both have the same cab and box plastics so it should be fine.

Just an idea, but my father (R.I.P.) used a trailer tounge storage box and it fit right in the storage area in his Z.

And the GSC 118L (SEI277) storage box fits perfectly too.
It's the fairly common one that Princess Auto (sometimes), HF, HD etc sells.

I bought the trailer tongue bow from princess auto on sale for $120 fits great and just as rugged as the ones that cost alot more
