I can offer an alternative suggestion.
On my 32 Sedan I tried to use the aluminium strips like in the CW Moss pics. I decided they did not fil well, as stated above they do not lay flat.
I bought some rubber strip from ebay. It is self adhesive but I went belt and braces and used some sealant / adhesive under it and stuck it on it looks great and had many comments about it amongst other 32 owners at a recent meet.
I'll show a picture of the product. It is very generic so should be available where you are.
I'll also give a link to my video showing it being fitted.
Not original but looks good and is better than the difficult to use and also non correct aluminium strip.
