Glad I decided to check this thread after a while of being M.I.A.
Vleds.com is the place I've went to get the #74 bulb but that was years ago until i found superbrightleds.com. If you go there and search for the same bulbs, the ones they'll have the bulb need and WILL have the bulb socket included.
To answer your question about the Svt odometer : Yes it should work, there's no difference IIRC. The link i posted will show the the type of bulb needed for the project. you don't need the high-powered smd, that would be an overkill nor the 360 degree one. Just get the 74-x one. I've switched between white and blue over the years i had mine, although i'm highly interested in seeing how the UV (purple) one will look against the LCD screen.
*Anyone that have any questions about the project, don't be afraid to send me a PM.
Like i said before, the project is not hard at all. just take your time and you should be fine.
