Spot on.

So, no truce then?

Agree completely. Never said they did. They change dies all the time though, same machine different dies. Same with stamping metal body parts. When they shut down B-body and F-body production in the 90's and early 00's to build pickups and SUVs they didn't swap out the presses, just changed the shape of what they press. Still doesn't mean a Suburban has the same frame as a Camaro.

The back of Seville/Eldo/Riv/Toro is essentially a trailer. Quite different than the back end of any Nova (except the awful one built by Toyota). It can be stamped out by the same machine, as can the frame for a B-body or pickup truck.

peter123wallace, something factual to contribute here?

Look all, I'm fairly sure this is not what scooter111 had in mind when he posted here. I've personally had my hands and eyes on everything we're discussing here countless times. I've presented pictures and other factual information. I've presented a case for why the Nova past isn't important to the Seville/Eldo/Toro/Riv as almost no parts fit both. I've tried to take the high road and stop the whole thing peacefully, only to be accused of spreading bad information. I will not escalate further. It's not that important and I don't need to prove myself right that badly. If someone needs to get the last word in after this message, that's fine, do what you think you need to do. I hope we all can find some common ground elsewhere in the forum but I'm going to stop participating in this discussion.

Yes stop spreading bad information the modified Nova frames stamped out by GM on the same frame stamping machines with different pucks.
Has nothing to do with a frames or other GM parts.
I did not know you worked at the GM frame stamping plant for 35 years like members of my family did
So all this time you have been guessing trying to prove some point of part interchange.
The frames were modified stretched out or not with thre same frame stamping
machines to save 500 million on new tooling at the time
