Door end seal, pillar seals and lock seals...

Hi Gents,

Pretty hard for me to make the difference between these seals...

I'm I right saying that "Pillar seals", "U-jamb" and "lock seal" reffers to the same part?
YearOne don't have these seals for my application (1970 plymouth duster) they say. Do you know if I'm supposed to have those on my car, and where I could buy a pair?
I'm looking for a pair of door end seals too.

(Few parts are missing since I bought this car, and I figure it out as the time goes by.. Not easy for a Frenchy to find the right name of the parts in this particular case) ;)

Many thanks,

Nicolas
