thanks men,the threded sterring arms on the 74 dart setup they sold me for $80 complete w/lca`s,had me confused.looking at the 70,b-body disc set i got the same day 4 my 70 satelite could see bolts going through the balljoint,did`nt know about the nuts on the roter side,thought it was the same on my satelite drum system, till i cleaned off the ball joint to see nuts on the ball joint side holding it on,the spindel match is good, using nuts+bolts from b-body drum conf.guess you can put bolts in front or back,i will put the nuts on the inside.
