Yeah, have the struts off, compress the springs so the top is free and then chop a bit off. finnish the cut end so that it is blunt not pointy! You can drill some small holes next to the spring in the cups and put afew wraps of wire round to hold them in. rears come out easy - and are even easier to get back in. straps round the axle (see my lx blog) or modded shocks (see franks) to stop the rears falling out.
