I have a 69 cougar convertible and I am new to the forum. I have had it in my garage for the last ten years...every spring I roll it out and through some money at it and roll it back in. Finally, I am ready for paint this spring. While adjusting the control valve nut, the spool bolt snapped off ( no I did not over crank it!)...anyway I would like to just replace the spool bolt without having to purchase a new unit...any ideas how to find one or am I just better off replacing the unit?
