1973 Plymouth Duster LCA needed

My son was forced off the freeway (driver on a cell phone) and spun out tweaking the Driver Side lower control arm. I had just rebuilt the entire front end from the PS gear box to bearings. Unfortunately he also tagged a tree which pretty much destroyed the rear quarter panel. He needs basic transportation for school so I am willing to help him replace the LCA and hope for the best on alignment. I have been trying to find replacement LCA's but not much luck, can anyone point us in the right direction? We would like to replace just the damaged one, since we will probably part out the car once we find a replacement (bad body damage).
Will we need special tools to remove LCA?
1973 duster v8, disc's with swaybar. thanks
