Doug, I bought mine prepackaged from Herb's Parts. I only needed 4 for my E-body Rallye dash and I believe there was 9 in the pack, for 23.00. A little pricey, but they work great, and are fully dim-able thru the full range of motion on the dimmer switch.

They come prepackaged for certain ranges of years for different bodies, A, B, E etc.
