7″ X 520.1″ 3-Ply Diamond Top w/MATO Rivet Fastener (Long Belt). The other size belt used with this belt is the 7″ x 513.6″. I can create a separate listing for entire sets if one isn’t already made. These Belts are Made in America and are OEM Quality. Don’t be fooled by cheap made imports that are advertised as American Made.
