I found some time off work and inspired by some of the threads on the restoration page I’ve stripped the interior of the doka and removed all the glass and seals. Replacing all the worn bits, cleaning up all the dirty bits and running Ankor wax into all the nooks and crannies. Im wanting to put on the new rear cab door seals and want some advice on orientation (note to self; make more notes to self during disassembly). Both the old and new rubbers, along either the top or bottom edge, has a rubber fin as part of its profile. I need to know if this “finned edge goes to the top or bottom of the doorway. Any ideas greatly appreciated.
