Hi, I got said coilovers for classic and went to fit them only to find that the spacings between the bolts on the top of the rear coilovers do not fit the holes on the car. The car is a jdm k plate wrx classic. The coilovers came from Japan off of a classic wrx of roughly the same age. One would expect said coilovers to fit, surely ?! Any help please. The difference between the bolts on coilovers and the holes in car is about 10 - 15 annoying millimetres. I was thinking about drilling, what d`ya think ?
