I'm looking to order a cwest wing for my 92 civic hatch, man I dig how it looks. I looked up on how they are installed, preety easy slips on over the stock wing, but they have pics of hatches with the jdm Oem sir wing only, wich is longer than the Oem one that's on my hatch now (Usdm). So my big question is, would It slip on my stock usdm wing or would it have to be a sir wing? Please help, an if anyone can post pics of the installation process would be nice, thanks in advance.
