well, i'm prepping the 74 for paint and taking the time to remove all the chrome trim. I figured as long as I'm popping out lenses, might as well replace all the bulbs. sooooo, the tail lights and back-up lamp. near as I can tell I have to remove the housing, pull it out to get to the screws which are back mounted to remove the bezel, lenses and finally get to the 3 bulbs which are twist and pull out. Of course, there's not much extra wire so I can barely clear the frame and it's quite difficult to get a screwdriver in there to release the screws. I also think I need to remove the housings so I can get to what appears to be 2 screws holding on the chrome trim around each lamp.
For the life of me, I don't think there's a way to replace bulbs from inside the trunk without all this work BUT this is so time-consuming I have to wonder if I'm totally missing something.
go ahead - it's OK. call me stupid. I'll take the shame if it will save me some work....
