Thanks, Vash. In your thread (http://www.fordraptorforum.com/f52/transfer-case-fluid-question-3336/#post709372) you mentioned that the spec for the T-case was 7mm (or about 1/4") below the lip of the fill hole. Still agree with that? I wrote to Chris at FreedomMotorsports because his recommendation figured so prominently in your thread. He hasn't seen my PM yet, but when he does I hope he'll weigh in. I'm probably not going to replace the front differential cover, but I'm looking to replace the transmission pan with a Mag-Hytec cover as soon as Chris can get his hands on them.
