92 turbo targa front caliper upgrades??

[TOYsORtowed]

What can I use? Having trouble finding parts at a decent price, will the ls400 swap work if I just find the calipers and a set of 17s? I found a good writeup on the process but its for a mkiv. Is there any bolt on, hassle free upgrades without spensing over $1000, or should I just get new, loaded oem replacements? My Calipers are entirely toast , the guy I bought the car from was trying to kill me, both sides were missing slider bolts so they started hopping on the rotors and siezed on me. Upon inspection I discovered capped off, empty bolt hoes where slider bolts should have been, on both front calipers! I took onse side off, bench broke the sliders loose, messed one up but remachined it, got everything proper and much to my disappointment, cant mount them safely because I cant find new slider bolts
