All the original petcocks had the ears pointing back to the block. The replacements that are sold, even if they are GM point in towards the radiator
Two photos of an original petcock. Flash made it look brighter than it is. Stampings on the back side. One example where an original part is different than NOS parts as the style changed with the ears reversed
Finding an original is hard. There are pet cocks available that have the ears pointing backward and are very close in appearance to the originals. One of the Camaro Legends judges has them for a very reasonable price. Like what you would pay for a GM replacement with the wrong way ears. Dale 804-405-1023. You can use my name Brad
