IMO, either would work fine. I've had good luck with just the part-store gaskets, but I've only changed my pumpkin once. If it looks pitted on the surfaces at all you might want a bead of RTV. You don't really need any gasket tack because the gasket will stay in place on the housing studs.
And don't forget those pumpkins are heavy when you're trying to lift it up into place & start some nuts! Now would be the time to put a rear end gear ratio tag on there too.

Permatex makes a gear oil specific sealer. Want to say the tube is grey with white lettering? It does work good and you can get it apart without using a hand grenade.
I stopped buying the generic blue and black RTV and have been seeking out products that are more tailored to whatever fluid it's making contact with.
I once put a Ford 8" rear together without a differential gasket and it didn't leak. If the two mating surfaces are flat it's totally possible.

Good info posted. I'm assuming it ain't gonna be coming out again soon. I would clean the surfaces well/get a parts house gasket/some Indian head brush on sealer. quick easy cheap. On a toughie (stat housings) yes "the right stuff" seals em when sometimes nothing else will (thermostat housing mating surfaces are too narrow).

To the silicone/sealer users: how much time do you spend scraping that off both surfaces? Thank-You...

I also use the Permatex Gear Oil specific RTV. I also use the gasket from any of the parts stores and use this sealant on both sides. I have used it the last two times I pulled mine and it has not leaked. It's a good product 👍

A thin smear of wheel-bearing grease on both sides of a good paper gasket has always worked for me. I really really hate leaks, but I also hate it when parts are glued together or you have to scrape gaskets off. This is what I do as well; only used RTV once and hated the clean-up when removing and reinstalling the unit. Grease and a Felpro gasket is cheap and easy.

As said (by some) just me I would not use RTV or TRS in that app, too much scraping to get the RTV off if you think you might be swapping pigs soon (most wouldn't be tho) & with TRS I'd about wanna put a nut on em & drive out the studs before attempting to scrape that stuff off. with cleaned surfaces expecially at the base of the studs, that a dry gasket would suffice, maybe a premium superformance one & even lubeing the gasket if frequent changes are anticipated. You do have a fairly wide contact area there. #1 check for debris.

If I ever go to experimenting with gear ratios, I will definitely try a good gasket and grease. I made sure both surfaces were hermetically clean before the thin bead of TRS. My memory reminded me to torque the nuts to 45 ft. pds---sound right?

iirc 45 yes. & hermetically clean is even more cleaner than surgically clean right! (no oxygen present?).

The "Right Stuff" is a very good product and will likely not leak.....Just pray that you never have to remove it because that stuff is the "Super Glue" of sealants, it can be a grisly task to remove it! This is true. I had to go back in and remove the whatever pin within the suregrip to use green bearings. I believe breaking the seal on the 3rd involved hydraulics. That being said, I don't really need to get into the 3rd member on a remotely regular basis.

To the silicone/sealer users: how much time do you spend scraping that off both surfaces? If you need to keep removing the pumpkin, you have more troubles than trying to get silicone off the housing.

Should have just removed the green bearings and left the 3rd member in there. Wilwood brakes require them.
