My '67 Overlander requires two certain light bulbs, an 1141F, and an 1176, which proved impossible to find locally. All the big, on-line companies sold one, but not the other.
I have finally found a "Mom & Pop" place in Missouri called AMT Electrical
who sold me both bulbs for a ridiculously low price. We're talking 16 to 18 cents
I ordered a total of 40 light bulbs which were UPSed to my door for a grand total of $10.36.
Their website does not list prices, but they do have a 1-800 number. Rosemary was quite helpful.
BTW, the 1141F, a frosted version of the common 1141, is now designated as 1141IF. The version sold to me by AMT Electrical looks different than I was expecting, but works just fine in my Overlander. The new bulb is on the right in the picture below.
