I need the interior paint codes for a 68 Plymouth Satellite. I need white for the interior of the doors and blue for the dash. Any help will be greatly appreciated!

Inner & outer 1968 paint chip charts & codes at http://www.hamtramck-historical.com/paintChipCharts/1968PaintChipCharts-01.shtml

Anyone know if the interior paint was gloss or flat? Thanks!

It depends on where.

Upper door frames glossy, dash frame low gloss as two examples.

The dash would be Bahama blue suede.

Thanks! That is perfect! Any idea on the inside of the doors?

"Upper door frames" = "inside of the doors".
UDF can be misleading to some since the lower part of the door is also UDF color. Masking line is the perimeter where the weatherstrip attaches.
You should look on Ebay or Amazon for a paint chart, as there are usually 4 different colors used.
R-M & DuPont both seem to have been suppliers.

Thanks!#
