Hi, I got a great deal on some used Tein coilovers. I am wondering if anybody here is good at decoding Tein's serial numbers so I can make sure what I am getting is right. I searched all over Tein's sites and a few forums but didn't come up with much. I believe the serial numbers on the side either say d6h58-11931 OR d6h68-11931, it's a little hard to see. Then under that number is says 10004. Also has anybody sent coilovers to Tein to have them rebuilt? Prices, shipping cost, and wait? Thanks for any help.

 

ttt?
