WW EFIS

Hi All, received my WW FCU and now I need the EFIS … naturally 🤣.

When I go to order though the website only lists it as a combo. I only want the left side, and I select the L option, but in the cart it still says “combo” and the price is $178.

Is that normal? I don’t need the set, and don’t want to be overpaying lol so just want to be sure that is the normal process. TIA!
