I had no trouble installing this crown jewel for transmitters...but the actual "depth" of some of the steering wheels can vary. So the very nice person (Ron) at GRID called me and told me that the wheel obviously had to be spaced out a little bit on the shaft. He mentioned that the phenolic spacer washers on the old brushed stock motors will work the very best...and they sure do too. With my wheel I used two of them. Now the steering wheel is perfect and away from the clam shell face as it is supposed to be. Her is a pic, and I will send a couple more a little bit later on.
