Kit or no kit

[62 Bowtie]

Was wondering whats a better route to take for bagging my truck buying a complete kit or pieceing one together heres what Ive got its a 62 c10 removing torsion setup and installing complete crossmember from a 78 gonna run dropped spindles and stock A-Arms remove coils and put baggs. At the rear remove stock coils and install bags in same location with a c or pipe notch not a big notch not trying to lay frame just sit low also no SS just up & down thanks, Tony
