Sure enough, I'm impressed with your drawing. Making and forming a spring from flat stock is of yet beyond my skills, but looking at those prices just for the aftermarket junk, could be worth looking into.

The reason I noticed the parts drawing was wrong is the terminals at the ends. Looks like the illustrators just took the wagon lamp and swapped light bulb drawings. I have the same parts catalog on fiche, page 221.

To Tom's credit, I've seen a picture before where someone installed a broken lamp with RTV sealant using a wooden stick cut to wedge between the driveway and the lamp while the sealant cured. If the bulb holder and lamp are the OE type, I'd consider this a long-term solution, especially with a new bulb, but those aftermarket bulb sockets look like something that Lucas would have come up with.


Here are some views of the aftermarket lamp in case you haven't had one in your hands yet.







These are a couple springs from an OE lamp. The black coating is flaking off, but the rust has just begun to weaken the metal.





For now, I'm going to keep my limited stash of old tag lamps. As dangerous as traffic stops are these days, I want to be sure these seemingly trivial items won't become someone's probable cause.
