273 dipstick tube length...Dads is...BROKEN!!

funny that they are all LA blocks and the tube is in the same place in all of them. oil pans same, oil pump (non hv) and pickup tube are same (car not truck) wonder why so many differences in tube length, a/c and such I guess?
I would think if both are replaced with oem parts, tube and stick as a matched pair all should be normal?
