the title says it all, i need to replace the ccm and i've seen several used 8N8962267A(the coupe ccm) for reasonably priced but i can't find any of the 8N7962267A(the roadster ccm) for less than 500ish, do i specifically need the roadster version, some sites i'm seeing say they are interchangeable but with my luck i'm doubting it. does anyone have any experiance with them?
