For I am Willys, hear me roar:

Is this an 89 half ton with the c/k body style? You would have to fab all your own brackets including a front hanger and a rear shackle hanger and shackle. I would get an axle, measure the spring pad width, then fab off of that. Use standard 78-87 1/2 ton front springs which are 2.5" wide. You would have to get the tranny re-worked to mount to a t-case and get an np241 pass. side drop t-case if you want a chevy front axle, or a np241 drivers side drop t-case if you want to run a ford axle.

If you find a king pin style dana 60 for the front, you can buy the Off Road Design steering arm for the axle and the pitman arm for the box and the tie rod ends. Then once you get the swap done, you call them with the length draglink you need and they fab one up for you[img]images/icons/cool.gif[/img]. It's all about 500 bucks. Thats what I'm doing on mine. If you go with a ball joint style axle like a newer ford or a dana 44, you can still use ORD's pitman and tie rod ends and draglink, buy have to have the knuckle milled flat on top for an arm, then get an arm from Off Road Unlimited or other places. You can buy a complete kit from ORU for a ball joint style that comes with a new knuckle already milled for around 900 bucks. And yes this is all crossover that I am talking about.

You can use the Off Road Unlimited SAS swap brackets like Willy's is using as well. The 2wd and 4x4 IFS trucks have pretty much the same frame.

You guys could find a divorced Ford NP205 and keep his current tranny.........[img]images/icons/cool.gif[/img]
