The code will be stamped in bottom flange. There were several codes used for 427s. Here are the codes:

The HD side yokes have bolt on caps for the u-joints. The small block vettes had straps that went on top of the u-joint cap and were held with two nuts at the back of the yoke.

Unless I've missed it, your '75 has the HD yokes. Apparently that was the last year they were available. There may have been a production line change after the diff was in, or maybe they just used up the parts which were being phased out and you got lucky.

caps are expensive these days look at any vendors catalog and they run $40 EACH. Some have used the aftermarket caps as well. You're going to need more then yokes to beef up the diff.
