Drum to disc swap question

I have an 82 Z28 with a drum rear and I have the rear out of an 83 with a disc rear. When I do the swap what else will I need? Will the brake lines need to be changed or modified?
Thanks,
Will

Yep, sounds right. I'd rebuild the calipers with the recall kit or you'll be sorry, thos calipers are prone to failure and freeze up.
