Why not a nv242? There's a 242hd amg version behind the 4L60E (or is it the 4L80E) in H1's and H2's. This gives you all the options of the Gen2 tcase with the 4wh, 2wh, a N position, and 4wl with the center diff locked. Dside drop, too. THere are sye kits that fit. THe Heep version needs a Novak adapter to bolt up to the same pattern as the 231, another $550...
