You could possibly cut down the original front Fairing cage, so there's just enough left to mount your original Clocks, plus adapt for a new Headlight.
There's SO MANY aftermarket motorcycle headlights on ebay / amazon etc. You'd usually pickup some generic Fork clamps to hold the Headlight in place, one each side (for a side mounted headlight).
Aftermarket Speedo's too, usually come with a 'universal' clamp to attach to your Handlebar. So no problem there either.
