Extending steering axle

I need a bit longer steering axle(?), this one is bit too short: Maladar told me about Tanida/Juran racing components and suggested that I also need a FET Quick release hub (Widric already has one) Beldin helped me to measure the needed length, we also tested a deep cone Momo steering wheel from Beldin’s FD3S (about 50mm deep, really nice but still bit too short) The result is somewhere between 90mm to 110mm, with Tanida/Juran 75mm addition and FET QRS2 (25mm more) I would have 100mm more length.
