I agree with Tony that isolating a shackle is a nicer solution. Now the horrid truth emerges; in almost sixty years of Seven ownership I have frequently resorted to the method you have used to produce a sort of Panhard rod, usually as a matter of expediency. It seems horrid but it works better than not at all. In your position of a semi rebuild I would take the trouble to isolate a shackle. Probably!
