Delco 1995023, impossible to find. I could never find an impossible to find NOS 41 switch so I bought this years ago. The only difference is a small tab that can easily be changed. I have a 41 donor switch. So... you can go either way with what's pictured. Keep it as a 42 to 47 or convert it into a 41. Price for the NOS switch is $275 plus shipping. The 41 switch is free. Please contact me directly at bobscads@comcast.net.
Thanks, Bob
