I had pictures of the interference and what I did to alleviate it in one of the links in my signature. But I have been unable to find them, sorry.

I didn't have a lift, your 2" should help.

I ended up cutting the corner of the pan and having it welded back on backwards. It worked and I never had a problem. To me the transmission pan interference is the biggest negative about an LS/4L60 4 X $ swap. I have looked into the transfer case that comes with an LS pull out and changing the front axle to a drivers side drop (which is what the 4L60 was designed to be used with). That option has its own issues.

You should be OK dimpling the pan?
