I need brake conversion help Power to Manual

[camaro__thunder]

I have the regular power brakes in my truck with disc on the front and I want to switch over to a manual setup or underfloor to gain some more room underhood and cleanup the firewall.. What setup should I go for ? I have seen this kithttp://www.performanceonline.com/sto...cat=448&page=3 and was wondering if I needed anything else for the swap ? Will I have problems stopping the 22"s with manual disc ? Or what about Hydroboost ? I am not that great with brakes. THANKS !
