14 bolts are actually really inexpensive due to the fact that they came in almost every 1 ton and 3/4 ton truck chevy has made. $800 for a truck is a good deal if it is running and in straight condition. The 14 bolt in the rear only adds to it. But if you look around, its not uncommon to find 14 bolts for $150. Its just super easy to make one fit in a blazer. But it is awesome that you have one because they are pretty much indestructable. There is basically no comparison to the d44. The 14 bolt is worlds stronger. A D60 is closer in beef, but still not as strong. You have to step up to a D70 to match it.
