Hack the old stuff out of there and weld in your new ones. They come from the factory? Thats a good sign, you cant go wrong with OEM.
Your never going to regret doing something to stop rust and stiffen up your ride.
Thats fine, but do you know if it is welded all the way or just spot welded, I cant tell on mine cause i POR15'd the piss out of it. For the record I think you can go wrong w/oem[at least for undercarrige] cant do any rear bushings because every bolt is rusted on wasy to much that they will prob just snap. Its like Nissan designed the car to rust on purpose-not a fan of disposable toys, i want to keep my baby
