How to tell a BB firewall from a SB firewall in a 1968 Camaro

The subframe is none of these that are on the the car. I have asked him many questions and he has answered none. I asked for a pic of the cowl tag which is not on the car too. I wanted to go see the car for a friend of mine  but he just won't answer anything so at this point I am just staying away .

Car has a '70 up frame on it. The way you can tell is by the elongated hole on top of drivers front frame rail. The rearward of three holes is elongated as they went to the charcoal canister in '70 and that hole is for the vent hose.

That is not a second gen subframe.  Totally different designs.

Early 67 frames do not have the large side holes. I have both early and late styles.

Warren may be suggesting 70 up Nova or service frame.

The frame in question is used on late build '69 Camaro's starting in Aug of 1969. The '69 Camaro did not use the charcoal canister, but the '70 Nova did. Camaro and Nova share the same frame.

Well whudaya know. It's a good day when you learn something new in my book. Here is my 08D 69 subframe with the elongated hole. I never would have given it a seconds thought.

The late build '69 Camaro subframe also used different sway bar bushing brackets. The earlier '69 frames, the hole distance on the bracket is 2 1/2" and the later frame used 2 3/4" spacing. If you ever need to get those later brackets they are also used on '70 1/2 and up Camaro frames.

Good to know. Thanks Warren. Thankfully my originals are good to go.

There were 4 subframes used on 67-9 Camaros (all interchangeable).  Access hole for bumper brackets, bump stop and the core support hole area are the main differences.  Warren is correct on the canister & sway bar.  Sorry for the late reply and short answer Friday.  Busy week last week and over the weekend.
