I have a gauge to go with my new form of refrigerant (not
R-12). It shows hi-side pressure can be anywhere from 25-45psi -
which seems like a big range. Not sure how old the compressor/lines
are, as the car (230M) had
engine replaced 20 thousand ago - and not sure compressor/lines was
included. Thanks for insight.

Is the difference that important? Would pushing it to 45 risk a leak?

I think you meant "low-side pressure". Don't put your gauge on the
high-side port. On my '99 model, the low side port is near the
windshield on the passenger side.

More is not necessarily better in this case. I'd aim for the midpoint
of the range Toyota recommends in the appropriate A/C manual on
camrymanuals.com .

That should be low pressure. If your high ranges from 25-45psi then
you're in trouble ;)
As with anything (such as wheel alignment), keep it in the middle of
the range.
