The cheapest way is to change the front upper and lower "A" arms and shafts, along with the spindles and brakes. Then you will have to change the rear end to a 1/2 ton 5 lug rear. You will need to have your rear section of the driveline extended and use a highbred universal joint at the rear end. WES

Not too much if you can find a donor truck. If not, it would just depend on what someone wants for the pieces that is parting one. I would be ready to spend up to about $500.00 for good used pieces. WES

That's assuming you can do all the work yourself. It's not a weekend project. To buy all the parts aftermarket and "new" would be way too expensive. Like Wes said... you need to find a donor truck. But I think you will prolly be into it for a grand or more...

The only trucks of this vintage to have 5-lug applications are the 71's and 72's. It would prolly be easier to find an entire truck that is in great shape to mount the wheels on... unless your truck is restored to cherry, and you are willing to put in the time.

One of my buddies did have a complete chassis for a 71/72 Half ton. He is in the Yakima valley.
I can check if you want me to. Do you have coil or leaf rear springs?

Otherwise it is off to the wrecking yards or see if you can find a craigslist or penny press wonder that is cheap enough that you can pull or switch the parts and send it on it's way. I'm way out of touch on prices for parts as I haven't checked on many for quite a while.

hi there :)

well you can actually use a '73-up as a donor but minor things you have to change but not a big deal

can use the entire front cradle suspension assembly from a 73-up only real difference is a couple of the holes that bolt the cradle to the frame need egged out a little to line up, and the brake hoses differ.

for the rear axle the shock mounts differ is all.


same 42.5" leaf pack distance otherwise

for 2wd


good luck
