Another 69 bucket seat question. This time on tracks

This 69 barracuda I am piecing together out of a stripped out shell was missing a lot of parts. I have bucket seat frames, and seat tracks. Do the 69 barracuda bucket seats require use of these spacers between the tracks and the floor? If so, I am missing them off the tracks. Dont need guesses, need definite yes or no about this specific vehicle.

Thanks
Matt

I`d check to see if the seat fits level , use shock rubbers if need be ---------
