I have 68 k20 project that I am rebuilding to a mud machine

and am looking to upgrade rear end to 14 bolt ff. I found one at local junk yard on an '85, is this a direct bolt on or can someone shed some light on the process to make it work. Any adive is more than welcome; This is my first Build. Thanks Ken

The one ton/k30 spring pad width is a direct bolt in. If you its a 3/4t, then the spring pad width will need to be changed. Its simple to change the spring pads, cut off the old ones or buy new ones. They are not expensive (compared to other things) Just have to weld them back on, at the proper angle of course.
