if your going to the effort of getting axles cut down you may as well put in the whole 10 bolt, I have one in my sedan, a fair bit stronger than the old banjo!

I am pretty sure that you can use the same tailshaft when you go to 10 bolt. if you dont have axles, what are you planning on using in the banjo?

[myss427]

There is a another fix, shorten the ten bolt to suit. Get 2 ford 9inch short axels, you do not need to cut or spline. Put ford ends on the diff and change the stud pattern. They are very strong diffs then.

I also heard that the short axle out of a VN is the right length to go into a 10 bolt in a torana

I once looked into fitted rear discs onto my SS. Rear discs were an option on LX, they used the same setup as on the UC, only the calipers were left to right. I'm fairly sure it would be a similar exercise to fitting the UC setup, only using the larger calipers and discs, welding and redrilling the axles. Having never done it, or looked that far into things, I couldn't be 100% sure.

whilst i was waiting for my mark williams axles (8 week wait) needed to get my car on the ground, my diff guy had some stock commodore axles laying around (28 spline) I threw 1 straight in and the other 1 needed to be shortened and resplined.

In other words if you want commodore axles only 1 side needs to be shortened and resplined.

so you could use 2 of the short ones then?

gday
got a nine inch with HQ stud pattern can ya fit HZ,WB rear disc brakes to,its a LH torana 1975 with out any problems
cheers

bango axles are same length L/R. the larger diffs centre is off set so one axle is longer than the other.
the vn short axle is actually 10mm short for lh, lx track but still slides in far enough to run.
the SHORT axle is usually ran as the long one and the long one cut down for the short.

After much thought on the subject, I have to decided to ditch the banjo all together, and go the 10 bolt option. Brocky reckons they are great in torana's and couldnt understand why race teams were putting in 9 inches. I could live with out the power sapping design of the 9 inch. Now i just have to keep my eyes out for a 1 tonner diff or a allready made 10 bolt.
I have a set of HQ stud pattern hotwires to fit so am not interested in commodore diffs.

just make sure you go a 4 pinion type as the two pinion type are no stronger behind an 8 or heavy 6.

[makka]

all 10 bolts that I have seen are only 2 pinion, its the BW,s that you could get 4 pinion

[Toranamat69]

If you do put the HZ discs on the Torana rear, make sure you get the longer backing plate bolts (with the large head with the flat side) and the 10mm spacer ring from the HZ disc brake setup as the Torana setup doesn't have them and I can't find where to buy these bolts. The wheel studs are longer too if you are changing them for new ones.

I wouldn't use a cut and resplined axle at all if using an LSD or a locker after having experiencing one let go under full power.
You are seriously weakening the axle when it is resplined.

Then again - no worse than the standard Torana axles.

They roll the splines in if they are to be strong axles - and they are raised so the root of the spline is larger than the diameter of the rest of the axle so the stress doesnt concentrate in the weakest part i.e. the spline.'

where would i get this done and how much roughly.
