So let's see. Offset to the passenger side, either a 1:1, 1.2:1 or 1.4:1 high range. 3.32:1 low range. I'ts full time 4wd with a center diff lock. No idea on the input splines, looks to be a female coarse spline maybe between 6-10 splines. Needs to have a long adapter to clear the pan on automatic tranmissions. There is an underdrive availble for it that has a 2.62 ratio that bolts to the back of the case, so it doesn't get any longer. But it's like $3000. A land rover isn't light, and they seem to hold up to swapped in small blocks and diesels (I found a 6.5 gm turbo diesel swapped into a rover in Austrailia ). Most kits revolve around th400 or a 4l80. Nobody seems to be making the th350/700 kit anymore. I hear rumors of a nv3500/4500 kit but no parts. There is also a sm420/465 kit out there somewhere. For those of you wondering why anyone would be interested in this, in a lightweight buggy you could run a driver's drop front axle in the rear and get 4 wheel steering. Or run a pass front diff upside down for a rear engine buggy. Just some "bench crawling" that Mike and I have been doing. I can't attach the pics to a PM, so I thought that I would share with everyone else.
