Howdy Miss Charolette and Iain, Ok, this is what i have come up with online. I know I havent looked long, but one of these links seems to list alot of Mercury capri kits by various manufacturers (The chicago capri club link). By the way, Mercury motors is a division of Ford motor comapny, here in the states we call them "Mercury Capri's". Now the other link is to a diecast model car, however its not the yr model you are looking for, but since I only have two links, I thought I would include it also. So, here they are, the first being the diecast link and the second is the capri club link: http://www.anticsonline.co.uk/737_1.html

Minichamps 1/18 Ford Capri 1969 Red (150 089000)
Although a fastback coupé, Ford wanted the Capri Mark 1 to be affordable for a broad spectrum of potential buyers. To help achieve that, it was available with a variety of engines. The British and German factories produced different line-ups. The continental model used the Ford Taunus V4 engine in 1.3, 1.5 and 1.7 L displacement, while the British versions were powered by the Ford Kent straight-4 in 1.3 and 1.6 L form. The Cologne V6 2.0 L served as initial range-topper. Until the end of the year, new sports versions were added: the 2300 GT in Germany, using a double-barrel carburettor and 125 PS (92 kW), and the 3000 GT in the UK, with the Essex V6, capable of 138 hp (103 kW).

This link has way too much info on plastic kits of capris by all manufacturers for me to list.
I hope that this info is of some help to you, even though I couldnt find the specific kit you were looking for.
Have a good day,
Greg
