Hey, I got the codes off the rearend - it reads 136 ZH. I can't find "ZH" in the code section. I'm certain it says ZH because I scraped the paint down to the bare metal. The 136 could be a 138 maybe, but I doubt it. Any ideas here?
Also, I think it's at least a 4.11 gear, but probably numerically higher. That's a seat of the pants guess, but I had a '66 Vette with a 4 speed and 4.11's, so it was an educated seat of the pants guess. Of course, it's quite likely that the gears have been changed. Looks like prior owner was using the car to drag race or street race.
