[Bill's 68]

Looking to replace the front springs on my 68 Firebird and wanted to see what brand others might recommend to immediately improve the stance. My shop guy uses Moog, but I have also been looking at Eaton (and possibly Hotchkiss). I'm not satisfied with my current ride height, which is about 1.5 + " above original spec, according to the 68 Service manual. I don't know what springs are on there now - probably no-name and/ or wrong part #.

Don't want to cut out a coil and cant afford to switch more than once.
Any recommendations appreciated.
