1969 rear end differential code - page from manual needed

hey fellaz,

I need a favor by a member who owns a 1969 manual to post the page where it shows all the rear end codes, I specifically need to know if TM code for 12 bolt O type rear is 3.42 posi and not open, I have the 1968 info but need to check out the 1969 page because http://www.442.com/oldsfaq/ofdif.htm show TM code as open rear.

thanks
Ed

As opposed to the partial documents in the GMHC download, the whole documents like the Chassis Service Manual and Assembly Manual (which have the information more detailed) are available in downloadable pdf format free of charge at Wild About Cars:
