The difficulty here is to plan ahead a space for the hydraulic (or any other) steering pump. They become very large in diameter and overall length and thus take up a lot of space on the dashboard. Drilling through the dashboard is an emotional and stressfull excercise. Check also the interpiece between the steering wheel and the hydraulic pump if you want to use automotive steering wheel. They just have different number of screws and different diameters. I had to adjust mine for the perfect fit. Plan the dashboard with gauges, hydraulic pump and steering wheel already during the early works on frames.
