These black steel seat brackets feature more mounting holes than the OMP HC/731E Tall Steel Side-Mount Seat Brackets (Part No. OMP-HC731E) for more mounting flexibility. The high-strength-steel construction allows thinner (3mm) material than standard (6mm) brackets without sacrificing strength. Fits most side-mount racing seats with 289mm (11 3/8") bolt spacing.
