No updates but I have plenty of time to think out here, so I have some questions. Not necessarily for this truck, but for a build I am planning.
The build will be an FJ45, dolled up like an early but running an injected 304/TH700, discs, air, steer and coiled front. Patina, but classy interior. I'm considering a 60 series axle swap [gaining enough width for Bundera, GQ/GU or 80 series coils], but for highway cruising I want to retain the 3.70's. According to this:
http://www.apexgarage.com/tech/gear_ratios.shtml I should get 109km/h at 1800rpm which is pretty ace for an old bus like a 45!
So, regarding the 3.70's..
a] will they bolt straight into the 60 series housings?
b] does anyone have any alarm bells going off [is this a bad idea]?
c] can you install an air-locker on these early centres [or are they too weak]?
d] will the truck be too sluggish off the mark?
Things to note:
FJ45 3 speed manual ratios are:
1st 2.757
2nd 1.691
Top 1.000
Reverse 3.676
The TH700 ratios are:
1st 3.06
2nd 1.62
3rd 1.00
Top 0.70
Reverse 2.29
Also, in my search I discovered this lil gem..

PS. Why is R in the Cruiser a higher ratio than 1st, but in the TH700 it's a lower ratio than 1st??
