[Saloon-lovers] 420 - difficulty with fitting rear windscreen chrome

Ever since I have my 420, the chrome strip was not fitted to
the rubber. Now I want to try to fit it but it turns out to
be a hell of a job.
The inner edge of the chrome should fit in the groove and
the outer edge should clip around the rubber. Wherever I try
I can fit a bit but it goes wrong when trying to go round
the corners.

Surely I am not the only one struggling with this - are
there any tips to get this done? The rubber is still quite
flexible so I do not think (hope not) that I need to change
the rubber.–

Is it the small 420 or the large 420G?
They fit completely differently.
Is it the right chrome surround, and not one for the Mk2
which you are trying to fit to the small 420…–

It is the ‘‘small’’ 420.
According to the WSM the trim should be inserted after the glass
and rubber have been installed. But as I found out easier said
than done!–

This is always a struggle. Here are a few things to check
or try:

  1. If on installing the glass and lockstrip the glass is
    too far into the cabin it will tend to reduce the gap
    around the outside of the rubber that the chrome has to fit
    between. Similarily using too much compound between the
    body and rubber will distort things. Ideally one would at
    least trial fit the chrome before the adhesive sets up
    fully. Since your sealer has long ago cured, combined with
    the hardening of the rubber you may be faced with fitting a
    new rubber seal. (This is nowhere near as difficult as
    fitting the chrome in my opinion)

  2. Check that there isn’t anything(dirt, old sealer) in the
    groove where the chrome strip fits.

  3. Before trying to install, lay the chrome on the opening
    and check the fit, gently adjust the chrome using thumb
    pressure only, until it lays perfectly flat on the rubber
    seal around the entire stretch. Now check at the hard
    points (Just before and as the horizontal edges transition
    to the curve) that there is enough space under the lip to
    actually fit the chrome measured from outer edge to outer
    edge.

  4. there is a chance that your rubber isn’t the right
    profile, who knows what the PO had available at the time.

If you manage to fit these surrounds,you will be ready for
marraige. Sorry, but I did mine a few months ago and it
really was an extremely difficult exercise. Good luck!–

I seem to remember that there are small holes at the ends
of the chrome strips. Would it be possible to connect the
stript by means of e.g. safety wire and gently pull them
together until in place, then put the clips over the
joints?

Or is it just that the shape is way off?–

try and get some closeup pics of the way the originals were
fitted, and/or off saloons.data

The reason I say this, is the 420G also has an unusual way
of mounting the chrome at the front, which is not what you
expect, and you would not be able to work out intuitively.

Some say the reproduction rubbers have the wrong lips, and
this may be so for some, but as I said, in the case of the
420G, they go over the bottom lip (from memory)

I would always adhere them with black adhesive, unless you
want to witness your windscreen chrome flying backwards at
70mph–

My glass shop had no major trouble getting the glass back in
with a new rubber gasket but essentially gave up getting the
chrome moldings in place. I worked on it myself and with
some judicious bending at the lower corners was able to get
them in but the fit is not great at the lower corners. I
seem to recall that these never fit very well from new
either.–

A forum member sent me a pic of his XK150 with 6 suction
clips. These have a suction cup which can be places to the
screen, on the cup there is a lever which rests at the glass
on one end and onto the trim at the other end. The lever can
be adjusted to height / pressure on the cup. I have ordered
a set (of 6), they are available from Sealey, part number
RE006. I will try if I get the picture uploaded.–
