the parts mike arms i got did not have that second hole, since i was using wagoneer steering.. the drag link is bolted to the tierod.. i kept it as close to stock as i could, i did have to shorten it.. so i cut the long tie rod, since it was the most expensive piece..(able to get one at junkyard and then cut the Tie rod end off it..) saves money..
the flat top knuckles.. for donors..
1. 1976 & older Chevy D44's will have both
2. 1977 & newer Chevy 10bolts will have just the drivers side (but it will be drilled and tapped already)
3. 1974-1976 Jeep Wagoneer & J-Series Trucks
4. 1974-1976 Dodge 1/2 tons
you can try boneyards.. i have seen them on Ebay for around 75 bucks.. once and awhile.. parts mike does sell the knuckles.. not sure on price.. you will have to email him..
i also know of a set up here in a boneyard.. infact i know of serval sets.. probably around $75.. but i havent discussed price with them.. just saw them..
those disc brakes.. not sure if they will work or not.. your concern is correct... since some times with that rotation difference will put the caliper in the way of the flat portion of the knuckle.. i havent dealt with it so i dont know.. i used the wagoneer d44 stock brake setup with my knuckles which came from a 76 Wagoneer.. then used the ford rotor/bearing hub..
