Have you tried contacting Bill Davis @ Great basin Rovers in SLC? He has them and will build it to your specs. He's also a REAL authority on LR in general and axles/gears in particular. You'd be hard pressed to find a better shop to deal with. I had him build one for my 109 last year - totally a satisfying transaction and he has a good shipper he uses because it's a heavy axle set.
Good Luck!
PS - I'd place Bill at the absolute top in a list of people who really know Rover axles and their strengths/weaknesses. A veritable encylopedia of knowledge resides in his head! You won't do any better than him. Ck out the LR boards - anybody into LR should know Bill, he's that good...
