I adapted the TF BB kit to Spyntec manual hubs and highly recommend it. I did the master cyl upgrade as well and recommend it as well. There are a few other kits out there as well. We have been trying to determine what TF modeled their kit after and have concluded it's a clone of the stuff on the military J8. FWIW, we also learned that some export markets like Australia get bigger brakes than North America as standard eqpt. All that aside, cost wise TF's kit is probably as good as you'll get.
