[Tigers] Optional F4B temp sending threads LIST question

[Tony Somebody]

Does anyone know if the F4B that was an orginal Tiger option had the correct temp sending unit threads when delivered. I am thinking if the stock sending unit fits the F4B it would be the only proof that it was/is an orginal optional intake that doesnt match the later ones sold for other than Tiger SBF engines.
Knowledge or thoughts on this subject appreciated.
