Someone out there is selling the dipstick combo for your car that's a little different than earlier described. I know ... it's what I ended up with (maybe Ames).
The upper dipstick tube inserts upward from inside the oilpan. The flared end remains in the oil pan. It's tapped into place. The lower tube is then inserted into the flared end. It's recommended that the two pieces be lightly tacked together with a welder.
The only problem with this setup is that there is a very slight gap visible around the uppper dipstick on the engine side. Not the prettiest, but can be easily filled so no one knows the difference.
I got sick of trying to get the correct tubes and finally opted for this combination.
