any suggestion for my servo fit problem???
Most standard servo should fit the car without a problem. I had KO, Airtronics, Futaba all fit on the car. Make sure the servo mounting blocks are installed correctly, and make sure that steering linkage that connects to the servo is the correct length (this will ensure that you're installing the servo with the servo gear/horn towards the outter edge of the chassis)
I looked up your JR servo in comparison with an Airtronics servo that I used, and the dimension is actually smaller on the JR (however, I'm not sure if they include in the measurement the "nose" you're talking about)
If the "nose" is causing problem, and you don't have any other servos to try, you can try shaving the back part of the steering arm, and also try a different servo horn that might be thinner.
You can also try putting servo on the back side of the servo mounting blocks and screw it securely from the back side (instead of screwing in from the front right now as per the instruction) this will buy you quite a bit of space away from the steering bellcrank arms, and you might have to turn the ballstud on the servo horn the other way to reach the steering linkage and maintain the right steering linkage angle.
