I did some searching (actually A LOT) and came across Cibie USA (http://www.cibieusa.com/cibie_aux_lighting.htm). He has the correct stle lamps (240mm) in both convex and concave. He has round buckets with the springs and other parts that can be bougt and used on your own fabricated mount.
Talk with Gunther. He helped me get some bulbs to fit my lamps.
