This bolt-in mid plate was designed specifically for our 1962-67 Chevy II frames. Laser-cut from .130"-thick steel, Mid plates include frame mounting brackets and hardware. Plates can be used with either Chassisworks' bolt-on frame or factory front ends. This plate comes without the lower mounting holes so it can be drilled to fit other manufacturers' styles of explosion proof bell housings (other than the Lakewood bell housings).
