D44 Flat tops are these correct

I got this axle for free from a friend.The bom is 603351 3 when you look this up its a 72 chevy k10 and that's what its out of.Have been readind Mr. N's D44 write up in his info the knuckles you need are 73-76.5 this axle is disc brake equipped these look right but this is a first for me.If they are correct they shoulb be a direct bolt on for a wagoner 44 right?Thanks guys

Yup flat tops and will bolt up to your waggy 44. And it has the better caliper mount to. Some have a big heavy steel one thats a rotor shield as well. I cut all shields off so trail junk wont get stuck.

I have those same knuckles on my 44, tho the dust schields appear to be in much better shape than mine.

cool.thanks guys I was hoping these were correct now I can start building this axle.
