Pookster-
TRF shocks have the bling but the shorty short short plastic ones (shorter shock bodies than the ones that came with your TA05) are much cheaper and work just as well. Either a Manta Tay or TA03 diff will fit- no real advantage of one over the other. You'll need bearings, obviously, and I like to use the metal motor heat sink- it doesn't really pull that much heat out of the motor, but it keeps the plastic gearbox from deforming when things get really hot, like in Memphis

You should consider the aluminum front hub carriers, too. I've broken and bent more than a few down there....
