The only info I have on shocks is what's in the P&A and the AIM's. The P&A doesn't list either, but the 67 AIM shows the 3192420 as being used on the base models. It doesn't show the 3192831. However, the 69 AIM shows the 3192831 as being used on the base models as well.
However, that doesn't mean they weren't used on anything else. Shocks were installed based on several criteria, so these may have been used with other applications as well.
