Guys its pretty simple if you like the amber angel eyes Pat has a quick ebay search will turn it right up, I found a set for $90 from Hong Kong.
I think he was mostly not saying much about it because its really easy to find, sure he could have posted a link but then again you could also PM him too I'm sure he'd help.
Trust me there is a member who used to be active on this forum who used to be helpful when it was beneficial to him and then as soon as you started asking for details stopped responding when he knew he wasn't going to get $$ from you. I've spoken to 4.8isX5 a decent amount in length and he's a good guy, just tryin to be unique, and we exchanged a few pm's/texts and I believe I was one of the ones to tell him to go for the amber angel eyes as its different and would look so euro.
Here's the amber eyes I found with just the search terms "e53 amber angel eyes":
