This 100% bolt in brace is designed to strengthen and reinforce your OEM 73-87 Chevrolet crossmember after notching for harmonic balancer clearance when doing a Cummins swap in your Squarebody.  Simply cut your notch in the existing crossmember, fit this brace and bolt in place.  Works with our Cummins conversion kits and everybody elses too! ******Please note that the OEM proportioning valve will need to be relocated.******
