Here is the 'skinny' on the overflow bottle....

In the end I did not mount it the same place as the TR4A. I use an air
dam that interferes with the area where the bottle would hang if mounted
using the righthand rad mount on the TR4. Instead I flattened the
bracket and mounted to the wheel well using the same bolt as the
overrider support.
Using the radiator mount would seem to put the whole works much lower
than I would have expected but that may be due to differences between
the rad mount on a TR4 and a TR4A (which I am not familiar with). This
is what it looks like...

(Originality disclaimer... blue & black wires and bracket on radiator
are for electric fan, air dam also partially visible).
Goodness knows why the 4s (with no-neck radiators) didn't have an
overflow originally as the radiator cap is such that it draws coolant
back in just fine as the engine cools down.
