Axle swap question

This is my first tech question since joining the ORG. I have a 97 F250 4x4 Powerstroke w/ a cab and a half. It might be called a crew cab but not sure. I do not have a straight axle in the front and prefer to swap it and the springs. The reason is it sags a bit. My old truck is a 99 F250 SD V10 standard cab. I am wondering if the axles are the same gear ratio. I have read a post on a different site that explain the tag inside the door but can not find it.

I will give you what I know about both trucks. The tag on the Powerstroke reads C9 under "Axle". The 99 which would be my parts truck reads C3. I know the parts truck has a Dana 60.

Your obs has 3.55's, won't work, find a ford 86-97 f-350 4x4 will be bolt in and if the axle is 94 and older you will have to mod the brake lines

The axle you have there is wrong ratio, and perches are wider than your current set up, it can be done, but not as easy

as kris said C9 is 3.55 LS and C3 is 4.30 LS. it is not easy or worth it, different bolt patterns and your parts truck has a D50 Solid axle you could swp those gears with the ones in your TTB.
