Will this work for a front disc conversion on a 1962 Buick Lesabre ?

I am planning on converting my 63 Chevy BelAir from the existing single master cylinder manual brake system to a dual master cylinder power set up. Will your Part# 916642205 allow me to do this and keep my drum/drum setup even though it is listed as disk/drum. If not, can you suggest a different Part# that is better suited for this conversion. Thanks for any help you can give me.
