Will a 2005 finned rear differentail cover fit on the 2004 and keep the rear end cooler?

i believe it will, i think its a common mod on the 04 rear ends.
It absolutely will fit!

Also consider a Stillen Cover, which holds almost an extra quart of fluids. Mag-HyTec is the best, and most expensive. It includes a place for a sensor to mount.
Any cover for a Dana 44.

I don't think so...If that was the case Titan owners would have had a finned cover (aftermarket covers for the 44 have been around for years)to install in 04' before the factory installed one...

Going by illustrations on www.maghytec.com, the standard Dana 44 has 10 bolts, and the Nissan has 12 bolts. Not much standard on the Nissan Rear, but that's OK. No Jeep will do what it does for me. :)
I looked on the STILLENS web site and didn't see the cover.

Sorry, my bad. I knew it was a bastard Dana, but to just eyeball it under the truck, the cover looks identical.
When I change the diff oil, mine will get a Maghytec.

Not in the name of time/money trying to get a new product on the market. Especially when you haven't realized yet that your product has an overheating problem.
I've done the switch out to an 06, the covers bolt right up, but you will need the brake line bracket for the year cover you get. The 04 bracket can also be modified if you have the skills/means.
i just did mine yesterday. courtesy parts sells the whole kit with everything you need (except the gasket... you'll need to add a tube of that before you check out). i took my time so it took me a couple hours, but worked out great. fit my '04 perfectly. i'd highly recommend doing this mod... if for no other reason than piece of mind.

also, my two cents on the oem finned alum cover vs. the AM products. if you look at the stilen and the other one (haytag or something?) they hold more fluid, but they have fewer and shallower fins. with respect to cooling, i'm of the opinion that having more fins is better than more fluid. the goal is to dissipate the heat. sure... more fluid will take longer to heat up initially, but once it's hot, it's hot. if you're not dissipating that heat, you're as bad off as you were before. the OEM finned cover has pretty deep fins and twice as many as the stillen cover (not sure about the haytag one). i definitely think it's the way to go. of course, others will surely disagree so this is jmho.

What did that run you?
what do you mean... cover wise or oil wise? i went with the oem alum finned cover with mobile one 75-140. took about 2.5 quarts.

or were you asking something else?

Sorry...How much did you get the finned cover for?
i think i read somewhere regarding stillen redesigning their diff cover possibly. i saw some owner's pix of oil bleeding through/out near the stillen logo. did a keyword search and found this,

130 bucks for the kit (cover, bolts, bracket) plus a couple more for the tube of seal and then whatever shipping was (i think like 15 or so).

I won't disagree...you're right, getting rid of the heat is the name of the game!

BTW...I just gave away a factory alum cover w/new bolts and cable bracket....for free...But it did go to another TT member.
