I didnt want to throw away my Koni's either, but in the end decided that there was more choice of front struts using the 34mm GD/GE spacing, rather than using GC ones. (I measured it at 34mm not 35). I was also trying to make it as much as bolt on as possible.
I have had a set of GD rear hubs shaved down from 36mm to 34mm so I can use a set of Tokico illuminas for a GE that I bought, but as yet I have not had time to fit them.
I looked at the possibility of using GE rear hubs but I am not sure the stub axle position is in the correct place compared with GC/GD ones and did not think it was worth the risk to find out after sourcing and fitting them.
