I bought some push rods from a guy on here and he said they were tsp and had a pic that said tsp on the push rods but when I got them I checked them and tsp wasnt on them all it said was MT7400x5/16-080
I don't know what the MT stands for, but the rest means 7.400, 5/16 diameter, .080 wall. They are good pushrods.
