taillights

[XxFWMxx@domain.elided]

I have a '77 scout 2 traveler and need to replace my tail lights. what are the
part numbers for the lights and where can i get them? I went to my local wal-
mart and their computer thing gave me a number but they never seem to have
those bulbs. SO i got some that looked like the ones that were in the scout
and put them in. well after a week or so the lower filament melts and burns
out. so now i need to find te right bulbs. 
  Thanks,
