Dipstick and stand tube

I have a 70 340 I can measure the tube and dipstick length tomorrow when I get home from work.
Also I have a couple of new in the box MP repo tube, dipstick that I can measure.
I would assume that all 318 or 340 are the same. I just recently took a tube and dipstick out of a 74 318 and stuck it in a 72 340 and it read the oil level correct.
I think the only difference between tubes and sticks are truck or car oil pan.
