[not for sale sorry]

will these drive shafts fit my 1973 engine and will they go into my hubs from a 1990 car, the engine is a 1275 and the hubs are from a 998 engine thanks shane

linky to drive shafts

Well IMO, the description is wrong..

The mah have disk cv's on the end but they don't look thick enough to be cooper S shafts.... and having crucifix joints on the other end suggests they are also non cooper S ( as they would have hardy spicers )

I assume you have crucifix joints on your gearbox and is the reason why you are looking at these..

[not for sale sorry]

yes i have the old type, not the pot type so was just wondering if they would fit?? what you think??

moved to tech

[not for sale sorry]

thanks for moving, any one with advice?

If you have either the Hardy Spicer or the rubber coupling inner joints, these shafts will fit. They will not fit Inner Pot type joints.

They will fit either disc or drum brake CV joints.

The Cooper S shafts are noticeble by a wide ridge half way or so down the shaft as can be seen in the picture attached

ok thanks so are you saying the ones in the link i attached will fit? thanks shane

Yes they will fit, are they cooper S shafts... No.

John, EARLY Cooper-S cars (like mine) do indeed have this style driveshaft. My car is a 1964, Hardy-Spicers came later.

As for these fitting where Hardy-Spicers are installed, No, I don't think so. The differential outputs are different on Hardy-Spicer cars. The shafts in the auction would be suitable for someone with an early -S like mine, or someone whose gearbox has the yoke outputs and wants to upgrade to 7.5" disks.

they are also rather expensive for what they are.

ok thanks guys i think i wont get them and just buy them brand new for the extra £100 pound or so, as the guy has not emailed me back, and i dont no what work etc they have done

thanks shane

There are only two 'styles' of 'driveshaft'

That is early rubber coupling/ hardy spicer (without distinguishing between Cooper S, for arguments sake) and Late Pot joint.

Have a search around

If you were talking about the inner coupling joints, then the ones in the auction attatched to the shafts are the early rubber coupling and yes they will not fit on a gearbox with hardy spicer couplings. But if its only the driveshafts you are after, it wont matter what coupling you have as long as its either rubber coupling or hardy spicer. Those couplings both have the same splines.

Also it doesnt matter what CV joint you use, Disc or Drum, both cv joints use the same splines.

Which leads to the question, what is the real reason for purchasing said shafts? Disc conversion? you only need to change the outer CV for the correct one. Inner coupling? is the rubber coupling the one you need or is it hardy spicer? or, are you just after the shafts to replace the ones you have? in which case as long as you have either rubber coupling or hardy spicer inner joints, they will fit, as said before.

Remember there are only two styles of drive shaft, distiguishable by the inner joint type. Pot joint or Hardy Spicer/ rubber coupling.

[not for sale sorry]

all i no is that i have a pair of pot joint drive shafts, but i am doing an engine conversion to a 1973 1275 so the drive shafts are diffrent and i just no that i need the old type i am not shaw of the name, thanks you for all your info very helpfull

thanks shane

Sorry if my post was unclear. I was referring to the driveshafts as a whole including the inboard drive "method". What I was trying to convey is that the yoke-type driveshafts were used on early Cooper-S. I was also trying to say that the output gears on the differential were different between yoke-type and Hardy-Spicer. That is to say, IF you wanted to convert a gearbox from yoke-type to Hardy-Spicer, it's not as simple as getting the Hardy-Spicer output flanges and putting them on the gearbox, it's my understanding that the differential output gears/shafts have to change. Please feel free to correct me if I'm wrong.

See the exploded parts diagram at this site:
http://www.heritageg.../gearbox/19.htm
and look at item 12 both in the picture and the numerical list.

Regardless, the auction has closed.

Well we got to the real reason for the initial question but will a 73 1275 not have pot joints? I supose it all depends on the amalgamation of parts, but I would have said if it would have had pot joints.
