I'm looking at a 67 Camaro with a Z23 interior decor group, What all does that consist of. I know from the trim tag that it has the Custom (deluxe)interior. Is Z23 the option #for that interior?
Thanks

The RPO for a Custom Interior is Z87.
The Z23 Special Interior option included several additional items (Pedal Trim - Chrome Pillar Mouldings - Brigh Roofrail Trim) that were not included in the Z87 package. Both options shared the Special Steering Wheel upgrade.
As the Z23 option was very cheap (@$10.oo) compared to the Z87 option (@$100.oo) it was pretty common for these options to be ordered together.
