Made of steel and zinc coated with silver chromite (you can spray paint over the chromite). From hole to hole measures 8.5" and from end to end measures 10". Hole sizes are 1/4" and offsets are approximately 7/8". Hangers are bolted to the frame (bolts not included). Bolt lengths and diameters would depend on original part sizes. Re-use or try to match the original bolts. We suggest stainless steel with lock-nuts.
