its not too difficult but as i have said before the coupe one is no bigger than the td/jtd one. if you are going to go to the effort buy a custom front mount one.
the hardest part is working out what piping you need (which isnt really that hard lol).
there is one on ebay for £3.99 lol haang on
no sos its just sold ive been watching it for 3 dayys and was gunna buy it as a spare but forgot about it until you just reminded me. the carriage was £12.99 so it would have been a cheap buy lol there is another on if ya look for a load of coupe bits off a red coupe hes got one
