The booster I bought had an adjustable rod on it and I was able to set that out the depth I measured with my gauge, but boy did I have to adjust it out a long way to make it work. That being said, all of the shallow pushrod depth MC’s like in the photo you attached that I looked up were for C20’s and not half ton. In fact none of the parts I looked up online from NAPA through all of the ones listed on Rockauto differentiated between manual or power brakes. They all list one number with no options listed. The only way I could find the shallow one was by selecting the 3/4 ton version with the thicker booster giving you the shorter rod length protruding from the booster necessitating a shallow MC. I even found a few write ups about it this morning on this site explaining the same.
So not sure I am making any headway there or the water is becoming more muddied.
Just to add insult to injury, on the correct MC, does the front port feed the front brakes therefore would the front port be considered the Primary Port?
