1951 Victoria rear ring/pinion replacement

[atch]

Hello folks. I've got my eye on a 1951 Victoria that's 7 hours away from me. A bit far to be running to look at it every couple of days. The rear is said to be original to the car. I've been reading about the rear gear ratios in these cars and it appears that available ratios were 3.73, 4.11 and some even lower (if I've got these ratios wrong that's ok; suffice it to say that they are lower than I want/need).

According to the current owner the engine's pretty much screaming at highway speeds. I'm looking to change the ring/pinion if I buy this thing.

NOTES:
1. This will be used as more-or-less a daily driver car.
2. The car has a Chevy 350 V-8 and power glide trans (1:1 top gear). Don't expel me 'cause of that. It's already in there and I want to have the ability to hop in it, turn the key, and go on 2,000 mile trips at the drop of a hat.
3. I'm not interested in swapping to an OD trans.
4. I'm not interested in changing out the rear for later (8", 9", etc.)
5. While I'm perfectly capable of doing #3 or #4 I don't need another big project; I've got a '48 panel truck that I've had for 48 years that is undergoing a major rebuild. I've got a half done '31 2-dr sedan project that I inherited. That's enough projects for me.
6. I only plan to have the car for a year or two while my "good" projects are under construction, then resell.
7. After driving it for a year or two I might decide that I like it well enough to keep it though. The car is a nice driver but absolutely not a trailer queen.

I don't consider swapping ring/pinion a major project and should be done in an afternoon. All the alternatives will have the car off of the street for extended periods of time. Remember #5 above.

I've read in some places that this rear is a Dana 41 and in other places a Dana 44. Neither of these mean much to me; I sorta know my way around 8" and 9" Ford rears but never even seen one of these apart. Does anyone know the truth (Dana 41 or Dana 44)?

I've been looking for ring and pinion gear sets. It appears that even if NOS existed that the ratios would be lower than I want. I've also been looking at the old Ford parts houses (Southside Obsolete Ford, The Old Ford Store, Carpenter, Drake, etc.) and so far haven't come up with anything.

Summit Racing shows a 3.54:1 set and a 3.07:1 set. Their listing shows they are both for Dana 44.

Does anyone know if these will fit the original 1951 Ford Victoria rear housing and axle splines?
