Gentex 313 / 341 Series Mirror
OEM for 2003 - 2005 model year vehicles
These older style mirrors are still sold through aftermarket retailers using the following model numbers:
50-GENK40, 50-GENK41, 50-GENK42, 50-GENK45, 50-GENK50, 50-GENK60

50-GENK40A, 50-GENK41A, 50-GENK45A, 50-GENK50A, 50-GENK51A
Looks like the 453 is the sexier way to go for sure. This guy sells on eBay too.
Pricing is definitely higher than some others though.
