I have a 1940 rear drum that I want to put on my 1947 car (its in storage) But
the studs don't seem very long. Will the rim/tire still mount on it ?

If it is a true 01A rim (1940) it'll work just fine as it is on your '47.
 
Actually this is a replacement drum that I picked up to replace my old one. The studs look shorter than my 47. My car is in storage so can't look at them right now. Were all the studs for 40-48 the same ?

Passenger car studs were the same between '40 - '48.

You mean a drum/hub assembly, not a reproduction drum, right? And, the studs you found were the same length as original, not something a parts book jockey handed to you, right?
 
Yes, its a good used drum/hub assembly I bought a little while ago. It is a 1940 drum/hub that I want to put on my 47 car.So I was hoping it would fit without any problems.
I am replacing the bearing and seals but wanted to know after removing the snap ring, how to remove the grease seal ? any tricks without hammers ?

Seal puller. Can get one at any auto parts store or online of course.

The seal is not usable once you pull it, so have a new one ready to install in it's place.
 
There are Wheel differences as to lug holes ! Innies vs outies, pre war vs post war. If lug nut only uses half of its threads, you will see the difference in length. Newc
 
Fit by bolt circle is the same, But the studs can be tooo short for some wheels. My forty with post war 15" had only half the threads used in the lug nuts. Newc
 
Yes, your '47 wheel will fit the '40 drum, but as has been said, the
lug studs on the '40 drum will be to short for a safe fit of the '47
wheel.
The '40 and the '47 wheels have different styled lug nut holes !!!

I had ask this question 6 months ago but did not get a reply about the wheels not fitting I guess I did not ask the right way. What are my best options now ?
