So I'm looking for a 14 bolt... And there's one here in town that has 4.10 gears, and welded spiders. I was looking for 4.56 gears, but I can't find any around here yet, so I was thinking maybe get this one and re-gear it. But will the spider gears be replaced with a re-gearing or will that cost more? I want to put a detroit in, as this is my daily driver. Thanks!
