63 to 67 dash cluster gauges - lens

[tprice]

Can anyone tell me if the glass lens in 63/67 dash cluster are concave or convex when assemblied looking from the drivers seat ? I have seen these both ways and need to know the correct way as far as factory assembly. Thanks!!!

Saw a body off restored car at Barrett Jackson with convex. The car bid $15000 under market as everyone realized, " What else is WRONG"

In 63 the factory lenses are plastic not glass....
