Originals are hard to find, but if you're patient and lucky you might find and win a bin on Ebay. Took me a year, but snagged these off Ebay this July. The right one had cracks around the posts and they were paint flat black. $20 in paint and one weekend and they done. I think they turned out fairly good. Oh yeah, the winning bid was $37 and they came with the emblems.
Good luck and good hunting.
