s13 FLCA Reinstall Question

[xbl1nd]

wanted to ask before I rely on somewhat common sense

I replaced my s13 flca with s14 FLCA with s13 ball joints

I am having an issue with my driver side FLCAmain bolt (the part that bolts onto the Knuckle).

During the removal process, you have to hammer out the ball-joint to separate that bolt that holds it to the knuckle, when I reinstalled it, it does not want to go back in so I placed the nut on, and tightened it enough where the hole was visible and allowed the cotter pin to completely go thru the bolt and be tightened..

The odd thing is on the passenger side, it slid right in, so my question is,
Would driving re-seat that bolt fully so there is no gap between the ball-joint and the knuckle?

Or should I reinstall and see if I can somehow get it to go all the way in with a rubber mallet or something

Again, the passenger side there is no gap, its all the way thru..
