Jerry, the September, 1968 P&A shows the 1969 support as being P/N 3937500 (Group 1.270). The 69 AIM shows it as being P/N 3938695, but no mention of any previous number. The 1975 P&A shows "1967-1969 Camaro" as P/N 3962940, but that's probably after a few service revisions since it covers all three years.
Does anyone have a 1969 P&A they can look at?
