Correct reproduction fuel tank for a '69 Barracuda

I'm seeing the same four front-back indentations on the Spectra Premium CR11C as on the 2nd pic…it's just the Spectra tank also has a transverse indendation (for '67-down transverse fuel tank straps). Doesn't look to me as if the transverse indent would interfere with using the front-to-back indents.
