[Classic1965]

Hi, I'm in the process of restoring a 1965 Chevy c10 longbox. It has a 12 bolt rear axle with 30 spline axles. It has 3.73 gear and I'll be running a 292 L6 with a 3 speed standard. What would be the best posi unit for this. I have a 17 spline posi from my GMC parts truck with axles, but I was told I wouldn't be happy with it. This truck will be a daily driver in the good weather and will be used to pull a trailer. Thanks
