I can send you the pages from my Classic Roadsters assembly manual showing how to relocate the pedal assembly. Since you are moving it forward, you may have to buy new cables for gas and clutch.
You may have some problems, depending on how for forward you want to move the assembly. There is a center hole about 2.5 inches, and two bolt holes (one on either side of the center hole. You already have these holes where the pedal assembly sits now. You’ll have to move the pedals forward at least so that the rear bolt uses the current front bolt hole. (I know what I’m trying to say here…but it will make more sense when you see the pictures.)
