Ah, ok. Slit should be deeper in the well.
But mine IS the factory top because it is date stamped on the inside. With month, day, 1964 and manufacturer name.
This car is better built compared to my 1968 and 69 cudas. Hard to believe they'd intentionally do this at the factory. But thanks for the possible explanation.
Any idea where the 24.5 or 26" bow height is measured from?
