D2 Track Chain

I've got two sets of track chain (rails) for my D2 5J, neither appear to be in good condition. The best of the two sets measures 3 1/8" in rail height--I haven't bothered to measure pin wear yet. Both sets have the pin bosses on the links worn by hitting roller flanges.

Can anyone give me the height of rails when new? Thanks.

my info shows rail hight at 3 inches for new and 2 3/4 inches for 100% worn
😕

You might have D3 rails at 3.19 new 2.92 100% worn????
dependzic numbers are good.
