Is a highsteer crossover kit all I need? And will it work with my original steering box?

 

You need to give a lot more info then that about your truck.

 

It's an 89 I'm assuming? Regardless of what it is, the front end is similiar enough. Yes you're IFS steering box will work, you'll need a High Steer kit, and depending on how you're doing you're SAS, you will likely need a steering gear mount kit such as http://www.marlincrawler.com/steerin...-box-mount-kit.

 

So if I go with trail-gears highsteer crossover steering kit I need this too?

 

And yes its an 89
