What should I buy for driveshafts for a k10 swb

[coggonobrien]

I'm moving my 4x4 blazer drivetrain over to my shortbox 68. obviously I will need some a differant drive shaft for the rear but when I do the swap i wall also install a 4" suspension lift. Should I go ahead and buy aftermarket driveshafts front and rear that are designed for lifted trucks or will the stockers be fine? the front driveshaft was new from lmc a couple months ago (came with the blazer).

Thanks,
David
