What does a jupiter one look like?
I thought Javelin & Jupiter were the same.

Why is the oil filler tube different ?

Further, the mounts need to be fitted on the special waisted studs.

The oil filler is shorter as there is restricted space behind the grill

What is the pipe in the picture of my radiator?
Heater connection? Was there a common reason this was blanked off?

Yep, heater port. TR2 and early TR3 heaters will work. Land Rover Mk1 or 2 might be the same part.

My car will be 70 this year, does anyone know what month it was born

The Jupiter registrar should be able to tell you based on the chassis number.

Thanks. I missed my babys birthday , & will need to have a late celabration.
On another matter I am thinking of replacing the cylinder head drains with heat sensors to get a better measure of water temp.
Is this a good idea of waste of time.
I am still struggling ti find 4 1/2 or 5 inch rims.
I have discivered that Ford transit dually back rims ate 16 × 5 . however here in Oz are rarer than Jowett rims.
Barrels from USA have a smaller centre than the Jupiter Dunlop centres so the cheap rims in USA are no good to me.
To me.

My last message ended prematurely .
A guy here can narrow six inch rims to whatever i want it justs costs more.
His advice is just look in wreckers . any one have an idea of a car with modern 4 1/2 of 5 inch rims?

There is a diagram of the wheel in the Tech Drawing section. There are no modern or even classic rims that fit PitchCircleDiameter
People have adapted VW Beetle 16 or Saab 90 15 but they do not look like Jupiter centres. Jupiter and Javelin wheels frequently crack and need extensive welding to fix. Plenty on JT about this.
New sets are available used for racing but of course are not cheap.

My Jupiter has temp sensors in each water tap hole. See SA rebuild topic.
