try ebay sometimes i see them on there. but rarely. as far as the bolts go, are you missing all the bolts or just the ones to mount the plates to the subframe? anyways when you put on the bolts/nuts make sure you get some lock washers for the bolts cause if you just put them on without them, after awhile the bolts will come loose. happened on my friends dx, he forgot to get some. i havent had to adjust mine since i put it on.
