Help!! I have been having a look around at a new trailer for transporting a 67 cooper in. There is 144cm between the wheel arches, is this enough or will I scrape the sides? The arches are only 20cm or so high with plenty of clearance above that height. The width is listed as 140cm and I cant get to the car at the moment to measure it. There was a topic about car trailers some time ago and they fit on a 5' wide trailer but wanted to confirm exact width before I got one.
