Back in the day... Austin Electric, Naperville, IL. I didn't get back to the restro until after Afghanistan 2008. Picked up several totaled Oldsmobiles, pulled the 307s and 2004rs and all the under hood wires and any odd ball stuff I thought might come handy in future.
Any more when I need stocks .. I just pull salvage, way less expensive. One thing to remember... Many of the Toyota is a copper silver mix for the automotive wire used. Has lower resistance and more stable during use.
