If you wanted to avoid an axle swap, Chevy used that rear end up until ‘72 and even made 4.10 gear sets. Most 14 bolt FF will be 4.10 or 4.56, but 3.23 and 3.73 gear sets were factory options if you need something that high
Huh, didn't know that. Though I still plan on running a 14 bolt, got a friend who has 3 late 70s GM motorhomes he wants to break down and told him I'd like the 14s from them.
