Drum is a floating drum & it sounds like the Brake Shoes / Lining may be stuck or the Shoes / Lining is "grooved" into the Drum
Be sure the Emergency brake is off & you could loosen the Wheel Cylinder bleeder just a little to release pressure & try to remove Drum
I will not continue...........Hope someone else can help
No need to reply.If someone else can help they will post
Many of these Fords are the same. I have taken several of these style drums off of 39-40 ford coupes, sedans etc with the "banjo" style rear with enclosed drive shaft. You are correct that the axle comes out past the drum and it has a key-way and key in it. Once you remove the nut and little cotter-pin that holds the nut in place, you should be able to get the drum off BUT you will HAVE to use a wheel puller. There really is no other way to get it off. If you dont have a puller you can put a bare wheel back on the lugs and just start the lug nuts about halfway up the studs and then make it like a "poor-mans" slide hammer and slide the wheel out with quick pulling bursts. I dont recommend this but if you dont have access to a wheel puller tool, it will give you something to try.
I hope this helps you.
I hope this helps you out.
I have used those adapters as well to adapt a small block to the existing "top loader" manual transmissions. The reason why many guys do just this is because YES you would have to replace the rest of the drive line if you went with a later model auto or manual trans like a muncie 4 speed etc. The drive shaft is "enclosed" in these fords and has a drive shaft tube that bolts to the back of the original transmission.
Let me know if you have any other questions. I would be happy to help.
