ive welded the outer gaurd to the inner and im gonna pot rivet the flares on probably..........i would have gone steel if i had the money to......if your good with sheet metal you could make some up yourself,or i spose would most panelbeaters do this you could get them to make the flares and fit them yourself weld them on preferably...what ever you do though try and reframe from cutting the inner gaurd from the outer as its bloody annoying to try weld up
