Ok thanks,,so that's how it goes..haha...but they are the same then yes...69 Conv.s with and without dual exhaust?? No exhaust plate welded on the driver's side like the coupes with duals??
My point is..would there be any difference in the conv. body with N10 dual exhaust or without so that would warrant the GM workers to write N10 on the firewall of convertibles? just curious?? I'm sure anything could happen...

I actually at first thought ZL2 was on the firewall for the cowl induction piercings, until I cleande further and realized it was Z22...
