I'm looking for a rear end with this ratio. Please let me know if you know where one is or if you'd take anything in trade..

If you limit yourself to the "large" center section, w/ 210mm ring gear, it will be nearly impossible to find one. However, if a "small" center section w/185mm ring gear is acceptable, they will be found in a number of W123 applications, where they are designated as 3.07:1.

I should add I'm after LSD...

I've got a couple w126 and w123 rear diff's. I'll have to check the gear ratio.
