You will limit your choices and have to accept lesser quality by staying with an all in one type kit. As far as not being sure of the exact installation of the different parts and which to use IE stick style push rods or Golden Rods, Z-bends or clevises...etc. just look to the local club. Pick a kit that appeals to you and go to the club and have them show you what accessories they use and how they are installed. This site is great for advice, but nothing beats the visual and face to face Q&A's.
