Just to give another opinion the 67 & up pans are wrong & I removed 1 from my 66 & went to Desert Vally recyclers in Phonix to get originals from them they fit well & now the cars ready for paint,they were slow in getting them cut & shipped but when I got them they were right for the car.So the only drilling was to change from bench set holes to buckets,that was a minor adjustment its best to use original for the older cars good luck John
