I had one a couple of years ago. I loved the look but couldnt be arsed with owning a ford cab in this country again!! Awesome when the weathers good but terrible when it bad!!
Fibre glass or genuine cossie arches are the options. F/G being cheaper and looks almost as good if done by a good bodyshop. (mine was F/G, but I bought it with the kit and paint allready done.)
At the end of the day though its still a Cossie rep! Didnt bother me when I was 21 but after 2.5 years of mucking around with various engines I finally got it back on the road and felt a bit of a tit in it!!
Stil cant fault the looks tho.
Good luck if you give it a bash.
