I have a 1967 RL411 (it's just like the SSS) Bluebird I'm trying to get back on the road.
You can see the panel I'm missing, the lower valance, that goes behind the front bumper. I think they are the same for all 410's and 411's. There are a few around, and yes I have checked the the well known 411 guys, but I want a straight - bondo free & rust free - piece. I know it's a long shot, but it never hurts to get the word out.
Peace
