O.K. I am getting old and I'm a dumb-shit. I bought a very nice 4:11 locker 9" to go in my Phaeton project which has a Versailles 9" housing. Only problem is that the carrier is early enough and does not have a level/fill plug. The Versailles housing also does not have a fill plug and of course I had the assembly together before the light came on that I don't have fill access. I am thinking that if I knew the actual gear oil capacity for an original fill I would fill it through one axle. I would only be screwed if I lost a wheel seal at a later date. What are your thoughts on doing it this way and does anyone know the capacity of an original fill on the Versailles housing? I realize this is not the correct solution, what are your thoughts?
