Sorry if this has already been said but I get the digest and
won't know until tomorrow. In answer to the question about the
use of original jack on the TR3, John Haynes indicated that the
hole was not necessary on the TR4 thru TR6 series. This is only
partially correct.
My 1962 TR4 (CT6716LO) came with one of these ratchet style
jacks that could be used inside the car. The TR4 frame has a
bracket just below this hole into which the 'arm' on the side of
the jack is inserted. The owner's manual (& reprints and Bentley
reprints) show pictures of this jack in use. Later, these cars
changed over to the scissors type jack but obviously, there was
no need to change the floor pans. Since the TR 5 (250) and TR6
models also used these floor pans, economies (read cost of
production changes) indicated that the holes should continue.
Hope this helps.
