Went to replace the plug wires on my 1995 LT1 engine and two of the plastic plug wire retainers were missing and one was broken on the right side of the engine. The only bracket present was the one on the accessory bracket closest to the distributor. My local dealer was able to order the plastic plug wire retainers but could not find in the parts book the bracket for the retainer on the accesory bracket furthest from the distributor or the one mounted to the side of the block about half way down the side. Any help with pictures or part numbers would be great.
