Machining Flat Top Knuckles

Does anyone have a machining diagram or the exact dimensions of where to drill and tap the three holes in the flat top knuckles of the D44's?

I'm going to use a small mill so I can drill my holes very accurratly if I know what the spacing is.

Also, who makes the best arms for the flat tops?
Are these just made from 1 inch mild steel plate, or is somebody making them from better quality steel.

If anyone has machined their own and has a diagram that would be great.

One more thing, what the story on the tapered sleaves for the bolts, are they really required?

Re: Machining Flat Top Knuckles

my setup is getting done now.. and im making my own arms.. but.. if you are looking into buying some.. i would wait to drill the holes till you get the arms.. im sure they are not all the same.. the general location will be above those 3 flat areas on the inside of the knuckle..
the tapered washers will keep a "snug" fit on there.. preventing any loosening up.. im not using them.. but instead.. 2 metal dowls pressed into it.. works pretty much the same..

Re: Machining Flat Top Knuckles

the tapered washers actually load the tension on the arm it self instead fo the stud, its WAY stronger, but alot harder to machine yourself.

I used a GM steering arm to pattern my knuckles, it came out pretty close, not perfect, so Im stucj with having to make my own extenstion arms, this is what I had planned to do all along, but I will use 1 inch or 1.5 inch cold rolled steel, Ive got some titanium I could use But, its only as strong as the fasteners, and Im adding the hardened dowels as JeepGod is using also because I cant fid the proper tapered reamer to fit the conical washers.

make sure and flycut the knuckles flat on top along with the machined arms, th4ese surfaces have to be perfectly flat to mate together strong.
