I have incorrect dipstick tube on my '37, would like one that was designed for the car. Send me PM. Thanks. ;)
PS. one I have has a Y in it with a open hole which I understand is not correct for that car.
This might be right for your car.

The '37 dipstick tube length is 15" from the entry point of the block upward (not sure of length into block) and the dipstick is 19.5" from the bottom of the breather to the end. The tube is straight with no breather port at the bottom. Harry
