Need front lift help

Ok so need some help, I have a 3" lifting spacer on top of my coils up front and my coils are strarting to sag, I have 285/75/16 tires with 1.25 spacers and it used to not rub on the bumper but lately it is. I need to replace them but trying not to spend over 300 because I won't have the truck much longer. Any ideas on what to do? I know a lot of people will say do eibachs and bilsteins but that's more than I'm looking to spend

 

Don't quote me on this, and I'm still trying to make sure it's true, but I heard that you could use the coils (and shocks) from a 1st gen tundra to get lift. I think 2wd coils got 2" and 4wd got more (not sure how much)
