The Honda Stepwagon / Stepwgn Owners Club

We have been trying to get hold of a towbar for our Stepwagon ("Y" reg, "RF3" chassis) - does anyone have any idea where we might find one? Is fitting single electrics a problem? Do you need to cut the bumper to fit a towbar? many thanks for your help!

Many advertised on ebay - probably about 8 to 10 different ones, but some are shown several times.
