Welcome to the forum! You found the right place to come for info, specs, parts, tips and tricks for our beloved 77-79 B-bodies.
Feel free to DL copies of the Fisher Body Service Manual, (the 79 one for you), parts ID lists, and any of the other info we have posted.
Rock Auto is a sponsor here and offers us a 5% discount on new parts. The discount codes are on their thread(s).
Someplace around I have one emblem, but I think I glued a magnet to the back of it so I could stick it to my refrigerator, lol. I'm pretty sure I used rubber cement so the magnet could be easily removed. If I find it, you can have it. I'll keep my eyes open for a pair for you too.
If you're interested, I have a 78 Caprice grill in fantastic condition. $75 Please see pic.
If you're talking the "L" shaped bright trim on the headlight assemblies, I have some spares of them too. $20 each. See pic.
If your headlight housings are broken, I have reconditioned ones.
They come complete with all the mounting hardware too. $149 each.
