How do I get the lift I need without shackles?

Looks like you need taller tires. 255/60-15's If your wheels are too wide for taller tires get some narrower wheels. Your's look like 10" wides. Put some 8" wide wheels with some 255''s to 275"s and rock the look.

Nailed it! That's the look I want for my 70 Swinger 340! Looks like B5 blue, too! mine has no vinyl top, and is a V88 stripe delete,. but your wheels and tires a perfect 1970. Hats off to you, Brother! I also have the vertical bumper guards, and I have the hood/trunk anodized trim, which I'm still trying to figure out how to redo economically. Beautiful car!
