New brake line kit question

[sherm6413]

Ok here's my deal: ordering a new stainless brake line set for my 69swb 2wd from lmc. It's a 69 frame cab with 72 front end and rear end with disc power brakes on front. Do I want the set for 69 2wd swb or 67-70 disc brake conversion set. I'm thinking its the later but hoping someone's ordered for this setup before. First guy I called at lmc sounded confused and gave me one answer and when I called again someone else gave me the opposite answer so here I am!
