Ok I used the search and I think I have my answer. I have found an awesome deal on a set of 3/4 ton axles for my 1500 Burb. Same year as mine, 1990. According to what I have read, these axles should bolt right in if I get the springs with the axles. Am I correct, or is this going to be a PITA swap? Both my driveshafts are variable length, but how much longer is the nose on a 14b vs. a 10b? I didnt have time to get measurements when I was out there.
