I've moved plenty of vehicles with less than complete suspension systems on trailers, and a few on a tow dolly. Stack up a couple of pieces of 4X4 wood under the spindles on the spot on the dolly where the front tires would normally ride, and maybe put a V groove in the top one with a chainsaw for the spindle to drop into. Then lock the front axle down tight to the dolly with a chain and a binder, or a big come-along. It will follow your tow vehicle just like the front end was all together.
