If
there are no mounting holes drilled by the lens manufacturer then you'll have to
drill and tap them yourself. If you know how to do that then go for
it. Perhaps check with one of the Imperial salvage yards on the screw size
of an original, especially if you're going for show quality "exact as
manufactured".
The
original screws were course thread, not machine screws. They should be in
the neighborhood of #8, maybe #10?
I
don't have a '62 at present or I would take one apart and measure it. But
I do recall from the '62 I used to have that the screws bit into the plastic and
worked fine. I never had a problem with them backing out. The light
bulb will go out long before vibration kicks the screw out, so you'll be in
there again replacing the bulb and retigtening things.
If you
don't have to tools for a DIY, a local machine shop would be able to drill
and tap to the screw size you want.
