68 c20 396 help

[veltex]

Hi all, I am new to the 67-72 crowd, just picked up very nice 68 3/4 2wd 396 air pickup, I have some questions if anyone feels like helping, have power brakes but want discs, will 71 3/4 2wd spindles, and brakes work? are ball joints and tie rod ends same? Other problem is cam going flat, I want to ditch quadra jet and manifold anyway, will probably pick up carb, manifold and cam set from Edelbrock, and maybe springs and have a valve job done all at same time, what heads came stock on 68 396? And will I get the cam in and out without taking grill out? It doesnt look like any fun. Thanks in advance.
