Found a 9" rear end for $200 that I'm going to look at tomorrow. I called the guy up, said it was out of a 79 or 80 model truck. I asked what gears it had, he didnt know, he looked for identificuation and could only tell me the number 7400. Measure length was 60". I have searched this site as well as pirate to find any info familiar to that. Anyone have any ideas as to what I'm going to look at tomorrow exactly?
