Hello. As most of you know, in 1939 Buick used a roller bearing for the pilot bearing in the end of the crankshaft.
I would like to know the diameter of the hole in the end of the crank where the pilot bearing goes. All '39s had the same bearing, so if anyone has '39 of any series apart, I would appreciate a close (accurate) measurement of this area.
Thanks in advance.
