SS springs overkill for my application, putting together a cruiser not a bruiser.

You asked for ideas, and said you were going for a vintage street car from the 70's. So in other words "The look".

Super Stock springs will give you the look.
And while your at it ditch the Rallyes and get a set of Cragers. Pure 70's look right there.
