Hey everyone. I have been wondering what size drum brakes both the cucv 14 bolt and the 3'4 ton 14 bolt have. Here's my dillema... I have a cucv 14 bolt w/4.56's and detroit and a 3/4 ton 14 boltFF. The 3/4 ton will go right in the blazer while the cucv 14 will require me to move spring perches and shock mounts. So should I pull the gears out of the cucv and have them put in the 3/4 ton axle or should i move the perches and shock mounts on the cucv? The gear/locker swap will probably be more expensive, but I like knowing all the angles are right and everything is welded correctly on the 3/4 axle. Back to the brakes, what is the minimum size wheel that I can put on the cucv axle... those drums are friggin huge! They make the 3/4 look soooo wimpy! One more question... is it true that if the carrier has four holes for the pinion shafts it cant be a gov lok? The govlock has to have three, right? Sorry so many topics, it's been tough for me to get good answers to these questions. By the way, this site it incredible! I find for more cool stuff on here. Thanks guys!
