Nightscrawlers

I read in marvel chronologyproject that Dave Cockrum appears in:

-giant size 1
-uncanny x-men #98
-Iron Fist #15
-Uncanny x-men #120

I didn't find him.
Can you tell me the page and the scene ?
Thank you.

I'll have to take a look at some of those when I get back home. I don't have the Iron Fist, but the others I can pull out and scan through.
