they are too thick they need to be inserted with the thinner side towards the control lever and then you still need to grind at least 1/8 inch from the side facing the rudder If If you don't do this, the control stick won't move forward enough to seat and you'll never be able to line up the front end properly. I cannot recommend them. I will never buy them again. I ended up buying a Moog k7040 kit. Bushings and they are ideal, the problem is solved.
