I know this seems to be a common subject but the answers are not clear now that I am staring at my two trucks. I bought an '88 one ton for its D60 front axle and 14 bolt rear and want to put them in my 78 blazer which currently has D44/12 bolt. On the rear, from everything I have read, it sounds like the only real work is to move the spring perches on the axle. Is there any necessary driveshaft work? Just before I found the 88, I spend nearly $800 having custom driveshafts made up for my blazer and am beginning to think I might have wasted a lot of money not simply waiting . . . On the front, do I switch over the entire axle and all the steering gear that is attached or what? Any help would be appreciated on this one. I know it is supposed to be an easy swap but nothing is that easy. I appreciate any help or thoughts or comments.
