The original pan was a 65? Corvair. The original SPCN title for it was 1970. There was no way to register it with a visit to the smog station. I spent plenty of time on the phone with the ref trying to work this out. There is no "legal" work around for this.So Party barge, I take it the car you built was abody style post smog and teh engine you unsed was a post smog engine. If that's not teh case, then you should have been able to regster the vechicle by the presmog part, car body or motor. Sb100 is the way to go to do that. people do it all the time.
