have a sort of a problem
i am going to put a 21in on the front, 3deg rake cups, 3deg wide glide forks, now how much longer than standed 06 dyna will the legs need to be to lower the front by about 2in. or by adding a total of 6deg will that lower it the 2in that i am after

 

I can't answer your question, but your bike looks great. Can you tell me what bars those are? How much pull back and brand, etc. Personally, I think 3 degrees in the cups and 3 degrees in the trees will be grossly exaggerated in the looks department. You might be ok if you try one or the other, as far as fork length.

BTW, you will probably have to get new handlebars too, because the angle will be so tilted back that they will probably hit the tank.

 

the bars are wild 1 560 low profile drag bar 4" rise, 30.5" wide 14.5 pullback
