BB A Body Coil Over Conversion

So i can buy the shock mount (upper) braces. Dont need tie rods, k-member, steering box. Can I use my stock lower control arms? Or stock uppers for that matter. Not familiar with this swap but if the rest works I would be interested in just the coilovers... I'm assuming this is simply to eliminate the torsion bars.?... BTW I'm putting a 440 in a 67 Valiant. Manual steering already, stock crossmember.
