Yo te aconsejaria Danas 44, aguantan hasta 36", hay localmente de todo, rotulas, cojinetes, retenedores, cruces, etc. Hay mas opciones en relaciones y sistemas de traccion(lockers, spools posis, etc) de fabrica y aftermarket. Facilmente se puede hacer un lincoln locker. Hay mas opciones de flechas, anchos, frenos, patron de aros, etc. Es relativamente facil soldar en las fundas brackets y bases de hojas. Tambien facil poder rotar los knuckles para tener el caster correcto adelante y atras. Y son relativamente economicos.
Un delantero de Wagoneer, catarina del lado de copiloto y uno trasero, que podria ser un trasero de wagoneer, el mas comun tiene el diferencial offset al lado derecho.
Si queres direccion atras, podrias instalar un dana 44 delantero que el diferencial estaria mas offset que el trasero.(diferencial lado piloto) Podes poner candados o drive gears.
De esos tengo de los dos primeros. Lo malo es que relaciones mas bajas que tengo disponibles son 4.27, pero no estan instaladas.
Lo unico malo de los 60's es el peso, el ground clearence (altura de cararina) y el costo del eje y partes. De alli, si es mejor el Dana 60.
Si queres un dana 60 atras con offset, para tener giro, tenes que usar uno de Ford, y esos son ultra escasos y costosos. Yo le vendi mi eje que tenia reservado para mi bronco a un cliente, en Q8500 y me queden sin eje Ford. Eso hace tres años.
Otra cosa es que que por el tamaño de los frenos, (mordaza) te obliga a usar aros de 16" para arriba. Otra cosa es el peso, el dana 60 delantero pesa como 520lbs.
Alli te van algunos datos:

Carrier split, regular cut: 4.10 down / 4.56 up
Carrier split, reverse cut: All use same carrier **
** Note: The carrier is the same for all Ford RC 60's UP TO 98, and is the same as the GM/Dodge 4.10 carrier - namely part # 706040X.
BUT - the Ford RC60 was never offered stock with a ratio lower than 4.10 in those years. When aftermarket vendors started making gears lower than 4.10 for RC 60s - they made the ring gear thick, so it could just go on the stock carrier. So if you bought aftermarket 5.38 gears for RC60 - they would likely be thick. Now - if you buy an aftermarket carrier (i.e. locker, spool, limited slip) for your RC60 - I imagine, depending on where you buy it from, they ask "year/make/model" and based on that would likely sell you the 4.10 down Detroit - that way - if you already had aftermarket lower gears, they would just go on the locker. The problem you might run into, is this:. You buy aftermarket gears first - lower than 4.10 and they're thick. Then you buy a locker by ratio, not make and model, and naturally you'd think "I have 5.13 gears - I must need the 4.56 and up locker" but you get hooped because the gears are thick, and won't go on that carrier. Also note, The 2000+ RC60 Fords are offered with stock gears as low as 5.38 - but these are not thick to go on the same old 4.10 down carrier - they are thin and go on the same GM/Dodge 4.56 up carrier. The carrier break is 4.30 and down go on the 4.10 and down carrier. I don't know if Spicer is the only manufacturer offering thin RC60 gears - but the bottom line is - when dealing with an RC60, you do have to match your carrier and gear set.

Front Dana 60 parts interchange:
The following parts interchange between Chevy, Ford, and Dodge front kingpin Dana 60s as indicated in the table below in the �interchange between� column, where C indicates Chevy, F indicates Ford, and D for Dodge.
The �Description� column is the name of the part as it is commonly known, and the column �Dana�s Description� is the description of the part according to Dana�s web site.
This info can be extremely useful when figuring out what parts can and cannot be used on an axle or custom project. Note, the absence of a part on this list DOES NOT mean it is not the same / does not interchange � it simply means that there was not a Dana part number listed for that part for all 3 manufacturers on Dana�s web site. This is usually because either a manufacturer uses their own part, own part number, or the information is no longer available. For example, the diff cover gasket for a Chevy and Dodge Dana 60 is part number 34687, but for a Ford it is listed as �Ford 60F variable parts table� when you look it up on Dana�s web site, but I�m fairly certain all 3 are the same. The same goes for parts like the diff cover fill plug and king pin cap grease fitting, which I�m pretty sure will all interchange but I can�t swear to it. In the same vein, you can use information in the chart to infer facts, even though they are not presented as such. For example, Dana does not list the same part number for Chevy and Dodge diff covers. However, using the chart we can see that the diff cover gaskets and even the cover bolts interchange, so from that, and knowing they are both standard cut low pinion Dana 60s, we can pretty safely infer that the covers do interchange.
