Does anybody have designs for Foward Controls for Harley Softail that would fit
a 2006 model.

which '06 do you have? and are the mounting points already there?

Heritage Classic. It has floorboards. I,m 6'4" and I like to get them a little bit more forward than stock.

You might run into a problem. The engine guard might be in your way

I was wondering about that. I was really looking for some basic designs that I could tweek for my application.
