Researching: D60 LP 4.88 ring and pinion weighs 18 lbs, 7.17 weighs 26 lbs.

That’s a lot less steel in there....and I’ve seen you on the skinny pedal. 

Less steel
Less strength

FWIW my crawl ratio is right at 75 in first gear and most times it seems a little low for me so i end up doing most stuff in second.

If I go with 5.38's the crawl ratio is around 64 and change.

I think you would like that 64


My crawl ratio is either 58 in 2.7:1
Or, 81 in 3.8:1

I run mostly in 2.7 and if I need more finesse go to 3.8.  Your number is kind of in the middle. 

If I’m behind Clark I go  to 10:1 ...that’s a ridiculous 215 crawl ratio

Ok, I was trying to do the math and was I like how in the heck is he getting these numbers lol. I will probably just stick with the 5.38 gears. It sounds like the 6.17/7.17 gears are meant to be driven at higher than crawling speeds for any distance. They're good in mud drags for a quick short spurt. With the 5.38 gears this would be close to my old red TJ, the crawl ratio on it is around 50:1.

Is 50:1 with both tcases in low?

Not my 42rle. That POS has like a 2.8:1 first gear vs. 4.0 in the manual from the same year
