Thanks to Woody for the photo of the Ranco valve showing the type number and to Denny for his photo of the defroster cable placement. Exactly what I was hoping to get. Just went out and looked, and yes, there are 3 holes very close to where Denny's cable is located. I can mount my new cable there with room to operate it with no problem.
You guys are awesome and I can't thank you enough for your time!!
