My 70 Super Bee has the vin number 178431 on the block, tranny, radiator support. I was looking at the trunk rail and it has the number 74178 which is only five numbers compare to the six number of the vin. Th last three numbers are consistent with the first three numbers of the vin. The 74 has got me confused. I don't think the quarter was ever changed but I could be wrong. Anyone have any ideas. Thanks
