34's on 11a drive train

My sons series 11a oz army workshop 109 is in need of tyres,
I am contemplating retiring the 9/34 swampers from my rangie and instead of selling them for bugger all, putting them on the series.
My concern is that they may be too big for the driveline.
It gets only occasional use on medium tracks, but I have broken 2 axels on 750/16/s but I used to take it on hard trips.
To all the toy people out there; are series diffs a straight swap?
I am trying to do every thing on this vehicle on a shoe string budget .

If running standard 4cyl LR engine, it my raise gearing too much--even with a 5.41:1 overall top gear.

If it's not used on anything but medium tracks it would be fine.
IN fact it will raise the on road cruise speed to be quite useful. And with 1st being as low as it is you will still be able to take off on hills.
To put Hilux diffs under it wouldn't be too hard, except you would have to change the spring seats and new u-bolts and possible have to make some new flip plates and a hi steer setup for the drag link.. Good idea if you want to spring over. they would almost boltr straight in, redrill the diff flanges for rove and make a drag link and hi steer.
But As I said for the use to are intending the SII would be fine, and at worst it WILL break an axle before a CWP

My main concern is rear axle strength, and I don't want to modify the thing much , the young fella is only 4yr old and by the time he can drive it on the road it will be celebrating it's 57th birthday.
Maybe an early manually locking jac mac would be a solution .

The bolt operated McNamara diff lock will strengthen up the rear diff a lot! My brother had a ex army IIA LWB with a 253 and a bolt operated diff lock, and didn't start breaking things until he put 36" Silverstones on, then he started spitting crown wheels left right and centre. Eventually he fitted a McNamara hypoid rear diff, and that cured the problem.
If anyone tells you to put a Salisbury diff in, just don't put the 34's on, as you will have roughly the same ground clearance as with the 7.50x16's and the rover diff.
