I installed SN95 front and rear discs on my SVO. I have an SVO Prop Valve that has been gutted and plugged. The front L and R lines are in the stock position and the rear brake line runs from the rear of the prop valve to a Wilwood adjustable prop valve. I've researched all the 3-2 port threads as well as 87-93 Mustang 5.0 Brake upgrade pages. Improve your 60-0 times! and haven't found anyone who has tried this. It seems that this would be better than adding the weatherhead fitting to a gutted Fox. My spare Fox unit was damged and the SVO has already been gutted and prepped....Any ideas?
