Ok gentlemen, please allow me to add some additional information that should be helpful for those looking for these particular parts.
I'll post the two factory diagrams first so that it's clear which parts we're talking about here.
This factory diagram shows all of the front door and quarter window related parts for the 1967 Plymouth Belvedere and 1967 Dodge Coronet Convertible models.
And the corresponding part number listing guide for the above factory diagram.
Ok, so the parts that Mike is asking about are listed under reference number 49 with part type code number 23-64-269 in the above factory diagrams. When you then go to the 1967 Factory Parts Book under section number 23-64-269 this is the information that you will find in Chrysler's original format rather than how I've posted it below.

The reason that the above information is important, is because it shows that several other 1967 models used this same quarter window roller assembly that you're looking for Mike and some of those vehicles can still be found in local wrecking yards in your area or online.
I hope that this helps all of our DCR members that might need these particular parts.
