Hi

I have the rear part of the tar board/firewall missing - I have the 2 sides in place which are of the "waffle" pattern type

id like to buy a full set of the same waffle type -


anyone know where I can get a set ? (pref in Eurozone) and can I trim down or make the cuts of a std sedan kit to fit a cabrio ? as they seem to be different (year 65)
