First off, if this is in the wrong section please forgive the newbie and redirect me to the correct location.
I have a 1998 S10 Blazer and a 2002 Blazer, What years are parts compatible, mechanical and interior. Both 4dr 4wd 4.3L Vortec.
I have also within the last week attained a 1998 S10 PU Ext cab 2wd 2.2L
The interior looks very similar, what years are compatible, front seat forward interior. I am also looking to increase tire/ wheel size from 215/75/R15 on the S10 as they are heavily worn.

 

Hey. The two 98's are almost completely compatible,you will,however, find many little things that aren't! As for the two Blazers,dramatic changes took place in those 4 years:fuel tanks/pumps,ABS controls,and as you may have noted :interior appointments.
When I was doing a swap over from a 96 to 97 Jimmy,I found such minute changes,I figured:why did GM bother and not address the severe engineering flaws?
Also fairly sure that at least 235/70/15's will fit the stock rim and not pose clearance issues on a 2wd but going to a 70 series may affect speedometer readings slightly.

 

fix up the 2002 its a better Blazer

 

Not necessarily! It could be the worst of the bunch. Yea the 2002 is the newest but the 98's are only 4 years older. Depends on the overall shape!

 

if it was me i'd go with the 2002 cuz it worth more and maybe it has better features but if there are major things wrong then i go with the 98 Blazer. What wrong with the 3 chevy? you sould pput pic on here
