I know this thread is basically ancient but I'm modifying my rc10gt I got all the gt2 arms to fit which the rears where necessary because I fit the o.s. 18tz to the car and the spur I'm using rubbed the stock arms my problem I'm having is finding the right length dog bones so I can actually run the car as it's now just a tad wider the stock ones fall right out even a point in the right direction would be helpful I'll post pics when I get home
