I know this thread is quite old but thought you might still be interested in this info.
'69 RS L65
Deluxe interior- full woodgrain & passenger side dash handle, bright pedal trim, console, dash mounted clock, courtesy lights, and under hood light. This car also has the hand painted stripes over the wheel openings.
I've looked very closely and can find no trace of a pebble finish, maybe because of the late build going into April of 1969?
Is there any info you could use that I left out?
