This kit contains (2) laser-cut 1/4" mild steel plates that bolt to the left and right side of the OM617A engine block. They are at the maximum length you should require, and can be trimmed down as necessary. Factory studs/nuts can be utilized. Material is pickled and oiled A36, which welds very nicely. You weld your own material onto these 2 plates to create your own motor mounts.
