Use the disk brakes off of them on your front 77 axle
The front axle's spring pads are spaced too far apart and the rear axle is centered. You planning on changing tcases as well???

Are you after extra width or are you chaning to a centered reat driveshaft? I would keep the 40 axles and use the birfs and hubs and such on your axles. There is a recipe somewhere here I think if you do a search to make a centered rear using the cruisers diff and the mini's tubes. If you want wider axles why not some out of a FJ60?

AHhhhhhhhhhhhh, I learned something today
I thought they were a bit wider, but that make sense when thinking about it.In that case, I would DEFINETLY stick with the 40 axles....
which birfs are stronger/weaker
the 40 or the mini?

Out of Africa / North Africa
Mini birfs are stronger but the inner axles from the mini ARE different from the '40 series Cruiser. Check out "Tech Trivia" for the inner axle length differences.
Long side mini = Long side FJ60
Short side mini= dam short and only mini stuff. Shorter than a 40 or a 60
Mini birfs are stronger but not that much stronger than the 77 unit.

I think thats why I had in my head they were slightly wider then the 40 axle, the long side being the same as the FJ60s.
85-older minitruck = 55" WTW
FJ40/55 = 55" WTW
86-newer minitruck = 58" WTW
FJ60/62 = 58" WTW
(round numbers, but close enuf)
The mini front diff is further offset to the passenger side, and the spring packs of a FJ40 install will land "on" the front diff, forcing you to outboard the springs, much like a FJ60 front axle install does.

My rear axle uses a FJ40 center section grafted to 84ish minitruck outers, and uses 84ish mini shafts...width is the same as the stock FJ40 front.
inner axles are all 30-spline at the side gear, 27-spline at the birf, and the birf is 30-spline at the lockout
The 85 front axle does offer some upgrades to your current 77 tho....bigger/stronger birfs (slightly, but why not...) - large pattern knuckles for strength and more hi-steer options down the road, and aisin lockouts. My 77 front axle runs the same mini-upgrades. (76-78 front FJ40/55 disc axles are morphs with small pattern knuckles and smaller diameter/longer shaft birfields...."most" of the balance is the same....)
