    Probably not. Ring gear location fore and aft is different between '32-48 and '49-53, and there is a strong possibility of problems with starter en and disen gagement...
    the difference is small, and it is possible it might work, but if you go for it fully check out starter function on a stand before putting it into a car. Screw that, just get the right wheel. They're not rare.

    ditto.

    Check out this thread, I had the same problem.

    I ended up buying a late flywheel (from a hamber) and having it redrilled for a lighter 9 inch clutch. I've put about 10K on this setup, works great.

    Another prob, likely covered in that thread (had some coffee, fog starting to lift...).
    I think the early wheel is the one with gear forward, and configuration can hit block or oilpump drive cover on late engine...again, possibly solvable, but more trouble than getting right piece...

    While we're on this topic, is there any big deal to shaving the old flywheels? Is it just a matter of having a lathe big enough to swing it and then use a cutting blade to shave off that bell? Of course, I would get the thing balanced afterwards.
