Should i change smths in the rear axle to let it fit k5 blazer?

Should i ?
 
for the rear yeah. any gm front axle will bolt right without doing anything to it. so if you have a 3/4 ton dana 44 or a dana 60 just remove and replace.
 
front shaft should fit i believe.the rear will need 1350 joint on the end or a convertion ujoint that matches the yolk you have now on the driveshaft and fit the new axle.the conversion joint will have 1310 on one side and 1350 on the other side of the cross.if that makes sense.i use one when i put in my 3/4 ton 14 bolt.measure the axle that is under your truck now to see how far apart the spring pads are.if that axle is 3/4 ton it will fit with no modification.the one ton is different spacing on the spring perches and the shock mounts.
 
you need the ubolt plates that hold them to the springs for dana 60 front or 14 bolt rear like in your picture . and ubolts will be bigger also. this is for the bigger axle tube dia over the 1/2 ton stuff.

and the rear spring pad width is 42" for 1/2 and 3/4 ton 40" for 1ton. this is center of the leaf spring pad to center of other side pad.

and driveshafts will be basicly the same on front but dana 60 will need to check length as the housing is bigger and that makes the shaft just a little shorter. but if you have a lift then might be perfect.

rear will need a trick joint for 1/2 ton joint to a 3/4 or 1ton joint. i dont recall the part # off the top of my head sorry.

otherwise its fairly basic bolt in job.

The Precision u-joint number is 447. Just did one tonight.
 
yeah i forgot about the spring plates and u bolts.they are what 3.5 inch on the 14 bolt if i remember correctly.
 
Thats mean i should change the place for each pad 2.5 cm ! Rit?

Measure what you have before even thinking about cutting. You might already have a 3/4 ton rear and those perches are already acceptable to bolt in right now. No mods necessary.
