ps. You folks can type too fast!

The Stage 1 has 3.54:1 diffs, so it you use one of those you also have to swap the diff back to 4.7:1 or use a 3.54:1 in the rear.

The Stage 1 CV's are an orphan not used in any other model, they are probably stronger than the yokes in the SIII halfshafts and are stronger than the later RR classic and Defender CV's but there are probably stronger after market CVs around. (Stage one halfshafts frequently fail at the diff spline.)

The 1 Ton helical transfer box uses the same housing as the standard series transfer box. The result is the prop shaft outputs are in the same positions.

And the WMS measurements?

Ok, so the front axle roundup so far.....

Strongest to weakest:

109" one ton Salisbury ... scratched as unavailable.
rear Salisbury modified for front .. I really don't need the extra work at this stage.
stage one ... ratios are no problem, but scratched due to orphan cv status.

109" one ton Rover ... am I reading this right or is this the same axle as the standard 109 from Sept' 1974 in which case either will do as they are the same unit?


Cheers,
Daryl.

With the exception of the after-market options, you've got it correct.

Yes the TT is cheap, then another AU$1000+ for axles (including CVs or HD Unis) Then machining and mods to the swivel balls and stub axles, and you are still stuck with puny 4.7:1 series diffs.

There is no cheap/easy way to strengthen a front axle.

Also, you've ended with an orphan after the machining?
And besides, it's more than I'm prepared to pay.

So, it's standard and common parts for me., which means I'll probably swap out for the 109. I'll start the brake research now.

Daryl.
