lowered springs for 69 cutlass

[aussie 69 0lds]

Hi

I was wondering if anyone could give me a measurement of the bottom of wheel rim to wheel arch on a 69 cutlass either stock or lowered 2 inch or approx 50mm

My front end is already apart and my suspension shop has a spring listed but I want to make sure it won't look like a RV

installed.The spring they have listed will give a measurement of 552mm

thanks

Andrew
