Since my Grenadier gets new rims and tyres anyway I would like to change the frontfacing wheel to a backfacing version. The pic is from trackparts, but there`s no special bracket in their shop. Does anyone know, where I can get one or is there any other solution to turn the sparewheel like it's shown on the pic? My dealer said it wouldn`t work with the original mount because of the bolts being to short to fit securely
