When did the mark one Cooper S cars change from Rubber Uni's to Hardi Spicer units?

Car No 1918 approx mid 1966.
From Dark Blue Mini workshop manual TP832 specifications section
It refers to engine number 1918 but that is the car number.
No S had an engine number 1918.

Thanks for that reference Ron.

I have been using Engine 41233 / 41234 as the changeover. Taken from the MK1 Performance conversions site. - http://mk1-performance-conversions.co.uk/gearboxes.pdf

But car 1918 has a later engine. I will have to update my list.

My first S was car No 1090 and had the rubber unis. Purchased July 66 from Gould's Motors in High Street Northcote. I don't know the actual build date but probably late 65 or early 66.
The LH one was replaced 2/3 times in 60K plus miles. RH one never replaced.
I was a bit peeved when I found that later build cars had the steel unis and the large oil cooler. IIRC they were added before the Bathurst 66 race.
I traded this in for my current S.

Ron - systematic change with blue hydro displacers being introduced at this same car #?

According to TP832, displacers were Double Orange to car 1917, Blue to car 3715 and Silver from car 3716.
Also Clubman GT Silver.

If by lefthand you mean the nearside, then perfectly understandable with some of our Goat Track roads! :shock:

The LHS drive shaft is also shorter than the RHS and for the same amount of wheel travel the LH uni moves through a slightly larger angle than the the RHS.
Is this angular difference enough to cause an increase in the wear rate of the LHS rubber uni?
Who knows.

As we drive on the left hand side of the road, left turns are sharper than right turns. So the left uni and boot get worked a lot more.

I've got one -- short left side driveshaft absorbs less torque than the longer right, meaning the left side CV has more torque load applied to it
