Are they the same? Found a clock, PN#6407595 [back of cluster, on circuit board]. Is this a '65 or '66? I have a '66. Will they interchange? Thanks for the help, in advance.
I know that 64 and 65 Skylarks use the same clock. Not sure whether 66's share the same clock or not. o No: I gave away my only spare clock, which was not working, so I can't check the p/n for you.
