yeah it looks that way but there are 2 cutouts, imagine its a clock
one is like 12 o clock and the other one is at 3, you get a screw driver into one of those cutouts and push the servo in and get the screw driver under the sirclip and pop it out, getting that clip back in is the bastard part... mine didnt seal %100 when i did it (looked sealed but wasnt, popped a servo out half the way up the road

had to limp it home in 1st gear
soo make sure you depress it heaps once its in again to make sure its sealed...
any more questions just ask!
