Hy 57DanR, all the transmissions you mentioned will present the same mounting problems as the 700R4 you initially asked about and the 700R4 is the only one with overdrive which will help with fuel mileage. The 4.11 to 1 gear set can be installed in an open carrier or a "posi" type if you can find one, I installed a Detroit Locker in mine, but I don't know if they still make one for that application, try looking on EBay or contact a good rear axle shop in your area to see what might be available if you want to go the "posi" or limited slip route, hope that helps.
