Default 1979 Corvette diff markings

I am hoping someone can tell me what the markings on my diff tell me about the diff. The markings are OH 235 WSE 1 (as best as I can tell).
Thanks, Colin

OH = axle code in 79 was 3.55:1

235 = Julian date code or 235th day of the year

W = Warner axle assembly plant

SE or 8E would be the Positraction source and year. Eaton assembled in 78. I believe if you look again, you'll see an 8. So, assembled the 235th day of 1978, or about August.
