[/quote] make sure the waggy front has flat top knuckles. 73-76(or 77?)you will also need ford hubs and rotors to retain your 5 on 5.5 bolt circle. not sure of the cost as i'm still looking for them myself. chevy brake calipers too. i think you can use the waggy spindle but i will find out for sure when i get my ford hubs. if they don't fit i'll try chevy 44 spindles. the ford spindles definitely will not work.

You're looking for 74-76 wag fronts, they use the small bearing spindle, the same as 70's chevy, which you will use with the ford hub/rotor. There is a rumor that some 77's use the small spindle, some use the larger. Finding spindles at the yard isn't that difficult, or even ebay for that matter. I believe the FLAT TOP passenger side drop front wags went until 78 or 79, but they won't have the correct spindle, but by adding those two years you'll probably be more than likely to find one. As for price, I've bought two, and neither cost me more than $125. Take an ad out in the local nickle ads and ask for Wag axles/scout axles....some of them can be had for as little as $50.
As for calipers you can use the Wag's, they are the same as the chevys.
Valley cat is right on to outboard the springs, but only if you're not going to cut down the axle a bit. If you do the Nutter narrowing 4", you won't have to outboard. When you add the ford rotor/hub, I believe you add .75" to each side compared to just running the standard wag or chevy six bolt pattern. Your final wms to wms width up front should be right around 59.5", and your rear will be 58" for the scout.
