I ordered a 15501 Lakewood. Whats weird is that the fork angle setup is per Novak instruction and a little forward facing (I forget the angle but it is whatever they spec). The fork is also in the front 1/3 or 1/2 of the window too. And the fork moves the entire range of the cable pull motion...it just that the motion it moves isn't far back enough. Now just to figure out how much to adjust this one. Is the GM 3790556 the one thats 1 1/8" from threads up to end of the ball stud? Do we know if that length is where I should be with my adjustable one?
