You can buy tow hooks at any of the chain parts stores. Not sure what you have in Tx, but I got mine at Advance Auto for like $10 each.
The hole spacing is different between TJs and YJs so make sure you get the right ones.
For the rear hook, you can either buy the factory Mopar hook or just get a 3rd one like the front and install it like this
Another option for the rear is to put on a hitch or a bumper with a receiver and use a receiver mount shackle
