3/4-16 Spindle Nut, Left Hand Thread

Looking for a castellated spindle nut for early Oldsmobiles that would have been 3/4-16, left hand thread, for the driver side front spindle.

Thanks!

It's a 1937 F37 Coupe. I'm guessing the 410901 part number would work as long as the thread pattern is the same.

No, My 1941 parts book shows #150253 fits all models previous to 1939. (1938 on back)

I can't seem to find that part # listed anywhere, however.

Your best bet is to look for a used one.
Maybe someone has a front end lying around that they cut out of their 1938 or previous Olds to put in a Fatman front end to make a streetrod.
