I looked into a Ford 9", yes they are strong, and
have good gear availability to match the 5.83s
offered by Calmini, BUT it was going to be about
$2500 to have one ready to bolt into a Track/Kick
Mind you this was including the gears, but

that's
a lot of bread man, So I continued the Full Floater
project, wanting to keep my Track, Kick as close to
Suzuki parts as posible.
As a note: I got the Calipers and a mount today, looks
good, i have a few more details to work out, but I think
this is going to be a really nice bolt on Mod, rear disk with
a Parking brake, easy to find and not huge expencive.
As far a spooled diff, the lockouts should not be affected,
and as far as strength goes, stock 26s are adiquate, not the
best, best costs $$$ I'm not saying it won't be available in
a larger spline count, but remember, these are going to be
a special built axle, and not an India import either, lets see
how they hold up, I will work on the bigger axles after the
prototype is up and running.
