I'm converting my Dodge dana 60 with external locking hubs to Chevy internal. I'm thinking about getting 35 spline stubs but i'm not sure i need it. i'm not a real hardcore offroader but it's not that expensive mod to do only about $140, and since i need new locking hubs i'm thinking why not? they cost about the same as the 30spline ones...so what do you guys think should i go 30 or 35spline????
