Planning my new frame...need some help

[Krusn64]

So I've been messing around on the computer trying to plan out my back half frame build...i have no experience with 4 link but i want to install a triangulated 4 link, so if someone could maybe take these pics into paint or something and draw some lines about where the link bars should go that would be a great help...i know that when it comes down to installing the bars my dad will know what to do but I'm trying to plan this as best as i can and he hates looking at the computer trying to figure out what I am doing lol.
