The control arms can be found on this site: www.truckshop.com, but to be honest drop spindles are alot cheaper now then they were a few years ago...
I say do the extra-cab swap & put the long bed on too...I myself have an extra-cab & just bought a longbed to this same conversion.
You can also post your parts on yotascene.com...its another great site for Toyota trucks!
Im not sure if they have them for your model truck, but some companies make lower control arms that bolt right up & give you a 2-3 inch drop.
