Jeep Axle Differential Identifier

"Dan, The Locking Tuffy Cubby Cover I ordered on Monday arrived on Wednesday! This was totally unexpected and greatly appreciated. Typically I’ve had to wait 7 to 10 days when I order from other venders. The cover was for my wife’s Jeep and was a birthday present. Very cool that it actually arrived on her Birthday!!! Not to mention we are taking a road trip this Friday and wanted to have the locking storage before we left. Also, I really appreciate that you post a PDF of the installation instructions for everything you sell. First off, it gives me an Idea of what to expect and if I even want to attempt an install. Last night I was especially appreciative as the Tuffy Cover didn’t come with instruction. No problem though, I logged on to your sight and carried the laptop into the garage. Thanks again! I look forward to doing business with you again soon. Michael "
