Do I have this sure grip option all wrong? On reading brochures from the 1960's and 1970's, what I interpret with the sure grip option is a 3.55 or 3.91 (or 4.10) ratio offered. I don't seem to find the sure grip option with 3.23 (or higher). However, I do find many 8 3/4 carriers (these days) for sale with sure grip and 3.23 ring and pinion. ??
