A.C. Compressor MOUNT 120R Small Block Chevy - Long Water Pump Passenger Side Product Description:
This bracket system is similar to our 130R and 230L, but sits about 1 in. higher to clear valve covers up to 4 1/2 in. tall when used with 1986 or earlier heads. Bolts to the heads and water pump. When the A.C. Compressor bracket is used on heads with one bolt hole, they will require drilling and tapping one hole for the upper mounting point.
