The '67 Pace car information board says three pace cars were ordered but it is thought only two were built. A friend of mine owns the L78 engine from the third pacer and the partial VIN on the block is in between the two other pacers. I guess that actually makes it the second of the three and the actual pacer for the race is the third one built going by the VIN. The NCRS report for all three VINs comes back identical, all three going to the Indianapolis zone.
