I build my own stuff triangulated and straight 4 link are a pain to build exhaust around especialy on a abody your charger has more room but slill tight.

I lke a tourqe arm setup best use stock front spring locations reinforce the stock shock mounts buy good coliovers your choice of panard bar or watts link and with no upper bars in the way lots of room for exhaust also no bind may be some fab time to make arm and mounts but all simple fab work and will drive like a dream.......
