Faulty 5 stud conversion

The previous owner used S14 knuckles on S13 arms/balljoints and S13 shocks.
The facts:
S14 knuckles have M14 bolt holes to bolt the knuckle to the strut. S13s on the other hand use M12. So this creates a dodgy joint between the knuckle and the strut, where there is a fuckload of variation of camber angle, ride height, etc etc everytime these components were unbolted as there were 12mm bolts in 14mm holes! Dodgy shit. Heres a crappy ms paint diagram to try and make things clearer.


What I had to do was drill out the M12 holes on the HSD coilovers I got to M14 and used M14 bolts/nuts.
Another thing is the ball joint issue. S14 knuckles/ball joints have a longer taper, and S13's a shorter taper. The previous owner had mashed the S13 ball joints into the S14 knuckles... damaging the taper, again creating a shitty joint. You can press S14 balljoints into S13 lower control arms (LCA's) but I opted to use S14 arms and balljoints to achieve wider stance (each arm is around 8mm longer) and some more negative camber without having to bottom out the adjustable strut tops on the coilovers.
