stainless tubing does not dimple very well , its too stiff. that's why mopar recommended copper tubing to be used for sleeving passage. it dimples very easily.
That was my main concern, that it would not dimple well. I don't remember the wall thinkness I was looking at, IIRC it was .032 or maybe a little less.
Screw it, I'll look and find copper. No sense trying to reinvent the wheel. Been there, done that.
