Does anyone know if there are any diffs that the axle shafts fit into? Ford 9", Cruiser 9,5", Dana 60 diff or something. I have seen alot of guys running chromoly, marfields and Longfields, cromoly and Long shafts making the 8" diff the weak point.
If there was a way to fit a bigger diff by simply clearancing the "cover" on the housing and drilling and tapping new stud holes and then stuffing the diff in there I think alot of people would do it. Not many people have access to a huge ass lathe or can justify the cost and hassle of an axle jig for one axle build. If one might be able to piece this together with OEM stuff found in wrecking yards, backyards and barns then many would try and we would soon find the best combination.
So does anyone have a big diff laying around and a spare axleshaft? That might be the first step, if something fits then we might be able to forego the custom shafts for something OEM Toy, Ford 
, GM, Nissan or other.
Many people have begun using the tacoma diffs in there diamond axles. I think it is comparable in strength to a cruiser 9.5". The conversion I'm talking about is not common because it is a hassel. I don't mean to make it sound to easy. It would take a long time it's just that it can be accomplished by someone with moderate skills.
The cruiser 9.5" takes the same 30 spline shaft that a 8" and 8.4" do. The fj60 front axle has a 9.5" diff. If I remember right it is 58.5" the same as an ifs rear. The outers are the same as a mini truck and will accept 30 spline longs. They also come with the vented rotors everyone swaps onto there trucks. I have seen a few mini truck sas done with this axle and I'm not sure why it is not more popular.
The same 9.5" comes in the fj80 and some come with E-lockers. Some guys over on Ih8mud.com have swapped this e-locker into their fj60 axles. It seemed to be about the same amount of work it takes to put a regular e-locker in a mini housing. Were the axles go into the diff one side needs longer splines for the locker. If you are getting longs anyway bobby knows the right spline length.
fj60 axle with fj80 e-locker. Not sure if this is front or rear they are both offset.
Longer spline needed for locker.
