KZ400 and 650 steering stem removal

Hello all,

I am swapping the front end on my barn find '74 KZ400 with the entire stock front-end left over from my previous '78 KZ650 restomod... The stems are the same wrt bearing sizes, however the 650 stem is about 1" longer. I need to swap the 650 stem with that from the 400.

After I grind away the weld, can anyone answer for me which way the 400 stem presses out of the lower triple clamp?
Same question for the 650?

Thanks!

Press out the stem from the bottom.
