Front Disc Conversion Kit

Doc, I followed the link, but can't tell what application this set is for. You say it's for early A-bodies.... does that mean it won't fit on my 69 Barracuda (with manual drum brakes)? Sorry, I am not that well-versed in Mopar... please forgive me if my question is stupid. In order to make this kit work on my car (if that is possible), would I need a different control arms? Or is it just not possible for my car? Thanks for any info.
