Anyone out there have any experience machining Chevy D44 flat top knuckles? From what I have read it looks like you set up the mill to just skim the rough cast off, then drill and tap the 3 holes. Is there a correct angle between the SMS and the machined surface?

wouldn't it be a balljoint front diff. if it were a kingpin front diff he wouldnt need to machine anything you could bolt on a steering arm.

Troy - It's a ball joint knuckle

Stink Finger - Thats what I thought, just machine perpendicular to the SMS, but that would mean I am taking off close to 0.125" of matterial at the high side and if I machined the whole top as in all the pics i've seen then I would have take out half the ball joint hole.

Big Block Chevy - Thanks, might give them a call. I have a CNC Machining center at work so I would like to do it myself.
