well i have no experience with disels but on my blazer it really wasant that difficult
it took me about 8 hours of work but i ran into bushing problems and i had to order pieces.
Fanshroud - easy no big deal
WIres lines ect - no problems
gas tank - no problems.
linkage for steering colum- easy cut and weld.
4wd linkge, mine wasant effected.
steering shaft - dill and it extends
steering colum - make sure to follow instructions about loosening so you can do nessicary adjustments.
ONE THING TO MAKE SURE OF!!! - DO ONE SIDE AT A TIME LIKE THE LIFT SAYS. YOU MAY THINK, HEY I GOTTA HYDROLIC LIFT LOOK AT ME IM LIFTING IT ALL AT THE SAME TIME!!! WELL THIS IS WHATI DID AND THE WHOLE CHASIS SHIFTED AND I WASTED PROBABLY 4-5 HOURS LINEING IT UP AGAIN.
