For the subframe connectors I am going to tell you to bring it to someone who has done them more than a few times. It is more than just slapping them on and welding them in place. The car nees to be at ride height fully loaded or you will end up permanently with a tweaked car. Get the full length MM ones as they are the thickest, strongest ones on the market and fit like a glove. If you get the bare ones, paint over the, and the areas where they prepped the underside with a good rust preventive paint.
I actually need to cut my SFCs off and replace them, the drive on lift was slightly tweaked and that transferred to my car, passenger door is harder to open.
