Match the lower mounting point
Compare the base curvature, mounting-hole spacing and upright-hole size with the bracket at your truck's lower cab exhaust mounting point. Check the 14-12998 or 21299 reference against the part being replaced. This curved-base pattern differs from the straight-base 21300 bracket, so confirm the mounting shape even when a listing names the same truck model.
Year coverage, hole dimensions and mounting hardware are not specified. Check the existing bracket and exhaust mounting arrangement before ordering.
