I just installed new front and rear window rubber seals on my 1961 Mark IX. The rear chrome trim was hard to put back in, but did finally go. The front window trim consists of two C-shaped pieces and we have been unable to insert them back under the rubber lips. Any suggestions would be most welcome.

this is an unusual Mark IX, 41,000 original miles, right had drive, stick shift, in specatcular no-rust original condition. It is a joy to drive.
