Hy Brian46Chevy, More research has yielded a Euclid part number E-4430B10 which has the dimensions of 1.119" X 6.34" and uses a centered single drawkey, hope that helps.
I couldn't source or cross that part so I paid way too much and ordered from Rareparts.com
I'm hoping that is the correct part but the guy on the phone at rareparts said they didn't have it/couldn't get it but I could email another employee to get a bid on them custom making the kit for me.
