SOLD -This is only a core and there are no guarantees, promises or warranties on this part. I am cleaning out my storage shed and finding things like this every day. Cross references to 66 Buick GS/Skylark. Stamped codes are 1100691 42A 6E19 12V neg and the date code indicates 19 May 66. $30.00 plus shipping from zip code 32904, which is in West Melbourne Florida. Please do not ask me to eat shipping. This will fit inside of a medium USPS flat rate shipping box and that is the way I ship things. If you want insurance the buyer pays.
