I have a 14bolt FF axle complete out of a 3/4ton truck. I've never gotten around to pulling the cover. I bought this axle with a matching D44 less that a year ago. I put the D44 in my truck and the 14b has set as pictured on the saw horses. Based on the front axle, this is out of a '74. As far as I can tell it is an open carrier. SOLD!! Um, I will not ship unless you want to make all arrangements. May be able to work out delivery, even as far as Junction if you're patient.
