P.S. The lamps are now reproduced and sold through NPD. The terminal is crimped. If you want the socket with the part number, they disassemble relatively easy. You could simply take the original braided wire from the new lamp.

http://www.npdlink.com/store/?p=catalog&mode=newsearch&search_str=15702&parent=0&year=01st, I agree that I don't like the job on the wire that was reproduced for the O.P, I thought I was alone so I didn't say anything earlier. I am rather in the same boat as the OP is (or was) I have an original lamp with only about 30 inches of wire before it was cut/spliced.
The mercury switch doesn't seem to work right, but it is possible I am holding it incorrectly when testing it (it seems to work backwards like it would stay on with the hood closed)
(directing towards somebody with an ORIGINAL, uncut wiring & lamp)
When comparing an unrestored wiring, fuse-holder and connector end that connects to the starter solenoid to the NPD unit, 1st question, does the repro even come close since it being sold as "exact repro" (yeah right, we've all heard that before) and...
2nd question, to reuse the original lamp housing and/or just the bracket with the Ford number and FoMoCo logo, how could the lamp be disassembled since there looks to be a "dimple" in the original lamp that secures the mercury switch and innards in place...I don't want to break either the original OR the replacement from NPD (should I go that route).
I ask because my original lamp, though not rusty, looks like a re-plating of the finish needs done to bring it up to concours level, therefore, a final question on "rebuilding" the original, I believe it was zinc plated, but was it BRIGHT or SATIN finish?
