Challenger front spoiler lip

[Eivin]

Hi Moparfans. I´ve searched all over, for a frontspoiler lip for my 70 challenger. I found few pictures with the exact model spoiler Im looking for - but not any up for sale - one of them is mounted on a 68 charger.

any ideas yo witch car that spoiler came from - and where I can get my hands on one like it??

Thanks
