Going to Hardies, can be an expensive option to get all the bits if you don't have them, but fairly trouble free once fitted.

Hard call in your case.

If the car is otherwise quite original and that's an appeal of the car, then I'd be inclined to stay with the rubber, but if it's not 100% original, it would be a period-ish acceptable modification to go all steel.

Slightly off topic and I know it’s been discussed before.
Drive shaft length/ interchangeably?
Cooper S hardy spices
Cooper S rubber cross
Drum brake rubber cross?

I’m using 333 box, HS outputs and S discs so which shafts length am I looking for.
From memory S shafts are 1/8 shorter?

Any advice please

Sorry, QH = Quinton Hazell

The QL-5000 is basically the Hardy Spicer crucifix running in needle bearings but with nylon caps instead of steel casing, so they can be clamped into the rubber coupling driveshaft flanges on the diff.

Minispares QL5000@ £59.40 pair or Rubber Coupling @ £26.10 each .. we are lucky Mini Owners given our repro parts are available & cheap.

Hardys are the Dogs or are they .. maybe a good Pot Joint makes a better solution ..sod originality & go for even better reliability.

I seem to remember a vendor (KAD?) was selling drive flange adapters. They had the splines for fitting onto the crucifix style diff output, but had flat four-bolt flanges so you could use Hardy Spicer joints on the driveshafts.

Edited:it was for pot joint diffs, and not KAD

I got sick of the rubber cross joints.
I now have Hardy Spicers, original (drum brake & rubber cross) driveshafts and drum brakes.

Hardy Spicer & Rubber Cross joint splines are the same
All outer CV ends are the same splines
I don't know about the length?

When I removed my Quinton Hazell's' the LCB exhaust had started to melt the plastic on one side
Mine is a 65 S, but I went for Hardy Spicers, far less troublesome than rubber.
Output seal is slightly larger, but instead of trying to machine the flimsy side plates, used same seals and skimmed output flange/ yoke.
Worked ok.
My excuse is a lot of people (not the ones on here I might add) think all S's came with Hardy Spicers!!!

Another point you should remember, if you are going to stay with rubbers is that the biggest killers with them is that people will insist in over-tightening the u-bolt nuts. They simply will not accept the low torque figure as fact. All overtightening does is draw the outer ends of the rubber tapers outwards. Another thing you must do is to radius the sharp inner edge of the joint mating surface. That is notorious for cutting its way through the rubber to start the whole train of destruction.

Considered opinion seems to be that if it's a road car, stick to rubber. Fast road car, QH's. If you're rich and want to spend money, HS's are the way to go.

Bit like what wrist watch to buy. They used to say that if you're just rich, buy a Rolex. If you're wealthy with style, get an Omega. But if you want it all, plus reliabilty, get a Longines. If you just want to tell the time, get a £2 texaco watch!

QH - 5000's for me. Much much easier to fit than the rubber crosses.

Of course , if its not original then “nearly” original is a useless conceit.

Pot joints are technically superior, smoother and more readily available....

Cheers, Ian
