so i have been slowly collecting wood trim bits and making a full set
for my 95 legacy wagon  so far have the 4 window trims the center vent
trim the radio trim and the shiftier trim. i have not yet found the wood
trim ash tray and the question i have is are there even side vents with
the wood trim available? i have been searching for almost 2 years to
acquire the parts i have now not that i haven't seen these parts before
just that i haven't found a set until this morning that was not broken
form someone ripping them off in the yard. but i have never seen the
left and right vent trim parts with the wood on them so do they even
exist?

I don't think they exist. I had a 1999 Legacy SUS 35th Ann Limited and if they were available, it would have had them. But it didn't

does anyone know of a wood grain decal sticker source that matches the original wood finish that i could put on the left and right  vents

You can buy that stuff on ebay and cut it to fit. No idea the quality of the end result though.

ive seen those on ebay i was curious if anyone had ever used them or know of one that will match the factory look.
