Inspection date was done on final inspection of vehicle that's why the stamp is upside down.

The white grease is typically a Zinc Oxide grease.

 

What is zinc oxide grease used for?

 

 

It can be used as a multi-purpose grease for many applications (up to 110oC). It protects moving parts against wear from shock loads in high load service conditions. Zinc Oxide Grease prevents scuffing and further assists in wear prevention due to the high performance EP additives.

Thanks Dave. I was just reading about lithium grease, this could also be an option. I have a mate who used to work for Castrol selling lubricants, I am waiting for him to call me back also.

Thats the third type of insp stamp I've seen.  Alway thought this was the inspection date of the heater box but makes sense that it is the vehicle inspection date.  Thinking about it the heater inspection date is actually on the fan motor.  BTW the first pic (25-5-73) is off a trentham built LJ.

So this begs the question which final inspection stamp was Acacia and which was Elizabeth?  I know which is Trentham.

I have a new batch of the heater box fan motor Smith's decals now available if anyone wants one or some. Just pm me.

As for the inspection stamps on the heater box there's quite a variety of them. Pre 73 cars tend to be on the side of the heater box near the wiper motor and are usually upside down but I have also seen them stamped vertically. Sometime around 73 they started stamping them on the front of the heater box and still upside down. My assumption is that since the stamps tend to be upside down that they were probably done when the heater box was upside down on a bench as that's how a completed heater box would sit the flatest due to the fan motor making it unstable when it's the correct side up. If it was an inspection stamp for when the car was completed then I can't see why they tend to be upside down.

Early examples are
INSP 74
1-MAR-72 as an example. They seem to have INSP followed by a 2 digit number. On the early ones the date is written with the month as abbreviated letters ie 1-MAR-72 etc.
By 1973 the format had changed. As an example I've seen
INSP SR
11-7-73
I've also seen SR on a 74 stamp which was
INSP SR
22-1-74.

Recently 2 NOS heater box tops went to auction. They didn't have these stamps but had the part number from the parts catalogue hand written on them in white.
