1940 Cadillac 60 Series 16" Wheels

[60 Special]

I am looking at a set of rims for sale and would like to verify a few things. Is the bolt circle 5 on 5", will the small hubcaps '41-'52 snap on, is the center hole the same as on '41-'52 rims?  I have already gone through the 900+ posts on the wheel forum and could not find these answers. Thanks! 60Special

41 to 52 hub caps fit the 39 to 40 16" small series wheels.  Hub diameter is the same on the 41 up 15 inch wheels as 39 and 40 small series wheels.  41 to 49 big series 16" wheels fit 39 to 40 but they are a 1/2" wider so the 40 full disc hub caps do not fit.  Dog dish hub caps do fit.
