Console Spacer correct or not?

[budman k20]

I'm about to install my non original factory console. I welded the original braces to the cab for the seats and when I bought the console I paid an extra 30 bucks for a spacer that goes in the front bottom of the console. The guy who sold me this told me this is the correct for 72. It makes the console top match the seat bottoms better. I never looked or noticed one on other bucket seat trucks before is there supposed to be a spacer under the console in a 72?
