I am thinking about putting assembly markings on the rear housing and center section of my 8 3/4. What would the stamp #'s/codes have been for a 1968
8 3/4 with 3.55 Sure grip or a 3.91. any ideas. Seems like hard info to find.
Just noticed that it only lists 741 and 489 center sections. I suspect the 742 would be similar. I have a 742 from 12/66 with 2.76 gears and a Sure Grip has 2 yellow and 1 orange (from front to back) There might be a bit of white right before the yellow but not sure
