Original Dodge Charger SRT8 Heckspoiler with ABE?

Ahoi! I had bought a rear spoiler for my Charger (2007) over ebay last year and pushed the assembly in front of me for financial reasons. Now I wanted to have it installed and found out that the ABE is missing. Google searches have revealed that you can send the documents about the manufacturer. Next problem: Workshop realized that the spoiler is not an original, and therefore has no numbers and so on. Ergo will we The ebay salesman unfortunately never answers and the 60-day deadline for an evaluation has of course elapsed for ages. Questions: -Can one still come to an ABE somehow or did I fire the 314,- € for free? – Since I am obviously too stupid to read and research, I also wanted to ask myself if someone here knows an online shop, the still original SRT 8-Heckspoiler offers and delivers an ABE immediately. I thank you many times in advance for any help.
