Quiz Related to 1967 Side Exhaust N14 and Ground Straps.

[Tom D.]

Not long ago, I went to a neighboring state for their annual NCRS Chapter Business Meeting. The host had a wonderful barn and an equally cool workshop. He asked us a quiz question about the (not yet installed) replacement (used) frame he had found for his 1967 Corvette.

He said: "How can you tell this frame came from a Corvette with side pipes?" The agreed upon answer was "there's no evidence of threads or ground strap witness marks on the cross member that under the car pipes would have passed through."

After a couple of weeks back home, I began to wonder: What if the frame in question came from a car with no radio? Could you still determine (from the frame only) if the car it came from had side exhaust?

Old and rusty frame, OK.

Restored frame: Minute with your MIG welder, proper drill bit, grinder and all those threads and witness marks can disappear.

The frame was old and had surface rust. The question remains: What if the frame came from a car with no radio? Could you still tell (from the old frame only) if the car had side exhaust? I think not.

Tom:

I believe there are three ground straps associated with the radio that are independent of side vs rear exhaust. So these screw holes could be checked for threads.

I am not certain it really matters one way or the other in the long run. If you are trying to counterfeit a side pipe car for NCRS judging, then make sure all the ground strap screw holes in the frame are "adjusted".

Of course, Larry, as you well know...trying to get the birdcage to pass muster may be a bit of a problem.

Yes Leif...........I have judged quite a few C2 cars in my time, and birdcage is one of the telltale signs. It is hard to duplicate.

The three things I really did not like to do during judging:

1. Give a total paint deduction after owner paid 20K for the paint job
2. Tell owner his engine has been re-stamped
3. Tell owner his car was born without side pipes

Larry I agree a person ( myself ) loves side pipes and will get clobbered for it. A person ( myself) loves knock off wheels and teak steering and pass with flying colors.

Those rear exhaust hanger locations can tell a story.
