Would you run these axles?

I like the screw in studs. I didn't weld mine but did locktite on the threads about 6 to 8 threads from the base of the head.
Either tacking or red locktite works well.
Hard to see but it looks like you have the new holes knurled ?
For sure RED loctite if I go with the screw in studs. The holes left in the pictures are 7/16" and had OEM studs already installed. That's where the knurl marks came from. I punched them out before the pictures.
So IF I go with the screw in studs, which I'm leaning that direction, should I get the 2" or 3" long ones? Will 3" be too long if I use the closed acorn lug nuts after it's all done?
