Not sure about all of it, but the 3 07 means it should be an open diff 3.07 ratio, and the 87 would be for a 8.7 rear end prob out of a 77-79 granada. the first group of letters and numbers should be a place of manufacture and possibly the dana ID? I think the last four are a date code but I don't know how to decode it Hopefully someone with more knowledge can help you out

According to the link here, WER-T = '75-'76 Granada, Monarch; 3.07 ratio; 8.75" ring gear diameter; non posi; 28 spline axle; non-removable carrier.

Or you can take a look on that same page above and see if there's anything that looks like yours.

Best way to tell what you have for ratio and posi or not is pulling the cover, but you can estimate the ratio by using the info here and check for being a limited slip here.
