When I took the front apart on my zook, one of the kingpins had snapped. I ordered some and they have arrived but are a different size to the ones that came out. Not a huge difference but I am no expert and don't want to stuff anything or have a dangerous car on my hands when I am done.
So... Is the difference in measurements a big deal?

They were measured using a ruler so to the nearest 1/2 mm but definitely different...
