Don’t do the Joey mod. Please don’t. Mine were chrome and my friend had a orange mini with the black ones. We traded those and she took my chrome mirror caps for her black ones. Just look around eBay, or cars that are being parted out on Craigslist. Be patient and look constantly and you will find them. snaptubevidmate
They come up on eBay quite often. Make sure you get all the parts, ballasts, bulbs and washers and these are not cheap. The washers can be swapped but be careful not to break any bit when doing so because dismantling is needed.
