the casting at the upper right side (numbers upside down) read c34155, i guess that is the casting for a 9+3/4" dana. at the bottom under that number there is a # 60 too,i am guessing that is a code fro dana 60 rear end. i do have the paper sticker wrapped around the oppisite side,it is hard to read the first few nimbers as they are a bit faded and one is being blocked by a brake line but here is what i think it reads- 8482081 or 3462081,the last 4 numbers are easy to read though and it does look like the 081 is for super track pack/4:10 gear,as that is what my car came with according to my fender tag code a34, daves code photo also confirms that it does match up.
