As best as I can measure, this is the bolt pattern for the steering arm studs on a flat top knuckle.

Can anyone verify these dimensions (or give me the correct ones if these are wrong). Don't want to ruin a good flat top.....

[New info 11-08-01] After finding Eric Ruhl's dimensions and double checking them with what I came up with, the angle in the above drawing is a little off. It should be 16.6992 degrees instead of 17. Sheeezzz I almost had it right............

Damn, 16 views and not even a single :flipoff2: !!!!!

Did I stump y'all? :D Certainly somebody here has drilled a flat top knuckle for a high steering set-up. If you have a high steer set-up, what did you use for yours?

:flipoff2:

Ya happy now? Ask Ben, he makes arms...

Ahhhhhh..... now my day is complete. :D Thanks for the tip on Ben. I'll give him a yell if he doesn't reply here.

Eric Ruhl posted the dimensions a while back in General 4x4, try doing a search there.

If you build your arm using the same dimensions you use when you drill your knuckle then you know it will fit.

I placed my high-steer arm on my knuckle, put a clamp on it, then clamped it into my drill-press vice. Bam, one hole. Moved the vice plate.. bam, two holes.. do you see what's coming? Rotated, made the third hole.

Removed the arm, ran my tap through the holes, installed the studs, then put the arm back down and used the tapered/conical washers, pulled out the torque wrench, and tightened down the 9/16-NF stover nuts.

Not very high tech, I admit.. but I don't have a CNC mill in my garage, so I made due with my Chinese drill press.
