Are these a mock hood pin? or real hood pin that mounts to the frame and really secures the hood? If real, what is the total length of the pin?

These are real hood pins, normally mounted where the stock hood bump stops mount at the core support. Typically, the pin tip to tip is, 3 1/4. There is 1 1/2 of thread, then, 1 1/4 from the end of thread to the center of pin hole, and about 1/2 above the hole, adjusted and held with 2- 1/2 nuts.
