I'm shopping for emblems also. From the ads the only difference to look for is if they are low pressure casting which look great, but, are very bendable. The high pressure or die cast ones are more rigid like OE. There very well may be more to it than that and is probably the case but I don't know what to look for. I still havn't bought any. I found the Trim Parts web page but was unaware that other vendors sold Trim Parts pieces.
