heard some bad rap about Russler. DRE advertizes $169 until you send the form in then it's custom made price. He claims center sump will be custom ,I explained center sump is standard Mopar to no avail. He claims he is the only one making diapers , so that gives him and NHRA the right to gouge. I don't have a problem with making my car safe , but I think having to pay through the nose to make that way is rediculous.
