I was going to use a ranger rear in my 28 model a but as I found out the axle is offset a little to one side so I picked up a mustang 8.8 instead and used two of the longer ranger axles I believe left side ones to make it 5 lug and the ranger drums they all use 28 spline axles so the interchange was easy. I am not certain but I could have swore the mustangs width was around 52 inches back to back...this web site might help you http://mjbobbitt.home.comcast.net/mustang/5lug.html
