CV Joint question, is there suppposed to be a gap? Options

[purple]

Hey guys, I was under the car last night and saw something puzzling.

There is a flange on the transaxle that the CV joint mount to. There is a small gap between this flange and the CV joint on both sides. It also looks as if there has been grease flung out of this gap. There is supposed to be a gasket in there isnt there?

Should it be a solid, gap free assembly from the flange all the way to the boot?

Could you guys post a pic of what your CV joints at the tranny look like? I'm really curious to see if the P.O. did yet another shortcut on this car.

Would red RTV work on this in place of a gasket? If indeed there is a gasket supposed to be here

Another question I have in this area... since it's obviously been flinging the grease everywhere and is likely not very lubed, what kind of grease can I use in there? Does it have to be that moly stuff?

I have some marine trailer bearing grease i had planned to use for the front wheel bearings. Does this work in this application? It's pretty much just lithium grease wihout a moly component, but it's breakover point is 500* +F the moly stuff is 350*F

Or do you guys recommend going with any particular type of grease.
And yes, I know not to mix greases. I'll be cleaning in there before I re-grease
