I've heard mention of an upgrade to a 1350 yoke for a 12 bolt. How does this work? Does it come directly off of a 14 and fit the 12? As I am not going to upgrade to a 14 until I blast my 12 to bits I would like to try this out. I think this may be sooner than later with my Detroit/4:56's and 37's. I'm not rock crawling here in Florida, mostly mud and trails. I know that this has been discussed before but what 14 boltFF directly bolts up to a Blazer? Just in case I come across on to buy whats a good price? What other mods need to be done to it? Thanks in advance.
