I am in need of a passenger side taillamp assy for 1988 Bonneville SSE. I've tried a bunch of NOS websites and Salvage Websites. Any one have any ideas?

Are there no wrecker yards near you, call them up.

Thanks for the input; however, I have tried local yards and been on a national salvage parts website. Got 2 hits from salvage sites, but both taillamps were worse than the one my customer has. I'm hoping someone might have NOS or a decent shape Bonneville that is used for parts.

Those Tail lamps are very hard to find... There were maybe 5000 SSE's made for a total of maybe 20,000 over 4 years... If found those Tails are like gold..

try look at bonnevilleclub.com alot of thoughs guys have parts laying around they will sell, i've bought a few parts from them in the past

Maybe if you search for an Used.
