with the coil front end it's going to be a LOT of work to put a coilover up front. the entire coilbucket on the frame needs to be cut out and then plated back in, and shock hoops built to hold the top of the coilover. and then it's going to be stock control arms, stock ball joints, and way more money spent than it's worth.
coilovers new will be around 1k ish for a 2.5x 6 or 8" long with springs.
install, unless you can do it yourself will be around $1800.
so you're in it 3k and still have a weak stock lower arm and fabtech upper.
you can see in the pic below how the stock coil bucket on this guy's frame was cut then plated back in:
