Try here. I don't know what the "9s" mean in two of them (possibly truck applications).

The one in the middle is a 1970, california-approved, chevrolet, automatic(probably, it's possible to have a 2 on a manual trans car) The other two are 1972, don't know what the 9 means, chevy, and one carb is auto and one is manual transmission. Keep in mind that since I don't know what the 9 means, all the other numbers could be wrong. I'm pretty sure about the middle carb though.
